lzw encoding/decoding now reads/writes the min_code_size byte
...
as such, lzw_decode now no longer needs min_code_size as a function
parameter since it just reads it from the source bytes

initial stab at gif load/save bitmap support

the lzw encode / decode algorithm seems to work well enough, but could

update rotozoom blit algorithm to something a little bit better
...
but there are still performance improvements we can make. but at least
now we're not doing some silly double-pixel draw as a band-aid over
missing/gap pixels. and we no longer sometimes have missing scanlines
due to floating-point rounding issues.

remove debug strings that would otherwise contain long strings of
byte arrays which most of the time isn't so useful to see in any kind

refactor blits, less copy+paste with slight modifications
...
this might still need to be tweaked still as benchmarks are showing
some performance loses (though, also, some minor performance gains?)
so i guess the lambda functions may not always be inlined, or if they
are, the optimizer isn't able to do the same level of optimizations as
it was before? unsure as of yet, so need to investigate further.
however, none of the performance regressions were huge, so i think this
is acceptable to me for now.
libretrogd was never intended to push performance boundaries anyway :-)

rename the old "apply" to "apply_to_device". meh. naming is hard.
i expect that most of the time i'd want to use the "apply" method i'm
adding here that handles device locking internally, so that is why i've
chosen to let it be called "apply" and to rename the other one.

return index of the audio channel instead of the channel itself

this is more useful because playing/stopping can be done on a specific
channel more easily by specifying a channel index. and the index can
obviously also be used to get the channel itself when/if needed, but
it's not super convenient to get the index of a channel when you only
have the channel itself
