------
Provides string manipulation routines.
length(str) -> ubyte length
Number of bytes in the string. This value is determined during runtime and counts upto
the first terminating 0 byte in the string, regardless of the size of the string during compilation time.
Don't confuse this with ``len`` and ``sizeof``
left(source, length, target)
Copies the left side of the source string of the given length to target string.
It is assumed the target string buffer is large enough to contain the result.
Also, you have to make sure yourself that length is smaller or equal to the length of the source string.
Modifies in-place, doesn't return a value (so can't be used in an expression).

find(string, char) -> uword address
Locates the first position of the given character in the string, returns the string starting

compare(string1, string2) -> ubyte result
Returns -1, 0 or 1 depeding on wether string1 sorts before, equal or after string2.
Note that you can also directly compare strings and string values with eachother
using ``==``, ``<`` etcetera (it will use string.compare for you under water automatically).

====
- move all str* builtin functions to a strings library module, mem* to the sys module. update docs.
- move target() builtin to sys.target constant
- use (zp) addressing mode on 65c02 specific code rather than ldy#0 / lda (zp),y
- optimize pointer access code @(pointer)? use a subroutine? macro? 65c02 vs 6502?
- allow byte return type with single register for asmsubs, for instance string.compare
- can we get rid of the --longOptionName command line options and only keep the short versions? https://github.com/Kotlin/kotlinx-cli/issues/50
- optimizer: detect variables that are written but never read - mark those as unused too and remove them, such as uword unused = memory("unused222", 20) - also remove the memory slab allocation
- hoist all variable declarations up to the subroutine scope *before* even the constant folding takes place (to avoid undefined symbol errors when referring to a variable from another nested scope in the subroutine)
