2abf6e2a06 Add class for resource filters in place of lambdas
This is easier to debug (printing out a lambda doesn't show what values
it checks against) and makes it easier to check that the filter values
are valid.

2b0bbb19ed Refactor filter_resources in __main__
With the new implementation, each filter is converted to a function,
then all resources are checked if they match any of the filter
functions. This is simpler than the old implementation, where the
resource lookup code was slightly different for some filter forms.

af2ac70676 Simplify ResourceFile._references and ._LazyResourceMap
The _references map now stores Resource objects directly, instead of
constructing them only when they are looked up. Resource objects are
now lazy themselves, so the previous lazy resource creation mechanism
is redundant.

_LazyResourceMap is now a simple read-only wrapper around an existing
map. The custom class is now only used to provide a specialized repr.

5af455992b Refactor resource reading internals
The reading of resource name and data is now performed in the Resource

in ResourceFile._LazyResourceMap.

f3b3de496e Change naming of compression types
The old names ("system" and "application" compression) were not really

8db1b22bdc Make the generic decompression API stream-based
The non-stream-based APIs still exist as before and are not deprecated,
they just act as thin wrappers around the stream-based API.

The main rsrcfork module doesn't use the stream-based APIs yet, because
it reads each resource's data all at once and not incrementally.

6559cbc337 Refactor .dcmp2 to be stream-based
This is a little more complex than with the other decompressors,
because .dcmp2 has to behave differently when at the byte before EOF.
Checking whether this is the case requires lookahead, which is not easy
to do with a plain IO stream.

Some buffered IO streams provide a peek method for lookahead, but
others don't (such as io.BytesIO). There is no standard way to wrap an
already buffered IO stream to add a peek method, so we need a custom
wrapper class and helper function for this purpose.

1e79dc3c50 Refactor .dcmp0 and .dcmp1 to be stream-based
The decompression code is more readable this way, because the
compressed data needs to be processed sequentially. It also allows
moving the length check and some debug logging into an outer generator.

This also allows incremental decompression, but this doesn't have any
practical advantage, because the compressed resource data is all read
at once (there is no API for opening resources as streams), and
resources are not very large anyway.

3a72bd3406 Remove leading underscores where they don't make much sense
The leading underscore is meant to distinguish private (for internal
use only) APIs from public (for external use) APIs. One can argue about
where the line between public and private should be, but if something
is used from other modules (as with read_variable_length_integer) it's
not really private IMHO.

In scripts (like __main__) it also doesn't make much sense to use
leading underscores, because the entire file is never meant to be used
by external code.

449bf4dd71 Use parameterized typing.Mapping in ResourceFile definition
Previously the un-parameterized collections.abc.Mapping was used, which
makes type checking less accurate, as the exact key/value types are not

97c459bca7 Change attribute type annotations to standard format
Previously, the types of instance attributes were annotated with the

instance attributes is to do so at class level without assigning any

be used anymore, and the types that it contains should be accessed
