updated sid tune
...
new sid tune is bigger than 4k, so charset had to be moved
now (part of) first half of the charset actually is used by the sid
and ignored by the VIC; chars had to be redefined

disk and tape loader
...
the loader is a small program with liblzg only, which loads data from
the snake.pack.lz (from either disk or tape), inflates the ram, and
starts the game

level loading colors with memory saving
...
loading colors was done in a dummy way by reading color of each tile
from the RLE array; but actually a tile always have the same color, then
this info is redundant; anyhow the character set had to be reshaped
properly in order to make easy infer the tile color from the tile value

Memory segments relocation and exposed bugs
...
- Declared uninitialized segment in zero page: used assembler directives
to reduce errors probability and improve code maintenance; now zeropage
variables addresses are automagically computed by assembler
- Added other debug messages, and rewritten some cycles for good readability and good software engineering
- Fixed more uninitialized stucture bug (maybe I had some sawdust in my
brain when I did this?)
- Fixed concurrency bug in home screen
