Updates to the assembler's output concerning the sizes of banks, how much are used, a --quiet option was added, and a -s option to produce a symbol map.

We can now create C like structs using .scope and .space, however, when we load zero page values from the symbol table, they create absolute addressed instructions, so that needs to be fixed

This is s a big rewrite including: A scoped symbol table, segment and
...
bank management, Use of promises to resolve symbols that are used before
they are defined. A base class for all instructions and assembler
directives. Hopefully my scoped symbols can be used to create C like
data structures in the zero page, ie sprite.x New code to prodce the
final ROM. Basically everything was rewritten.

Accidentally had the opcode for TXA be NOP, don't know how that happened. I ported background.asm from NESASM format to my format, it is veeeery similar so not much needed changing, and the resulting ROM worked fine :)

I have added many directives, such as .org, ines header, .dw, .bytes, and made it produce proper Roms launch into the entry point at 0xC000 from the reset vector. I basically rewrote the Assembler class, this could still use some cleaning up though, more unit tests, and to compile some code with CHR segments
