cc17c70e30 Fix reading/writing 4MB HiROM 
HiROM starts at bank 192 and has 64 banks so byte variable currBank overflows.

f07f6f9025 All: Replace print_Error(*, boolean) calls with print_{,Fatal}Error(*) 
Also, make print_FatalError(*) independent from print_Error(*).
Also, factorise common parts of print_Error(*).

Frees 2336 bytes of program space and 5 bytes of global ram space.

a35c882662 N64.ino: Factorise JoyBus-related code 
IMPORTANT: with this change, the Adafruit clock generator becomes a hard
requirement to read and write gamecart eeproms.

This is a large patch, partly because JoyBus is used a lot:
- controller
- controller pak
- gamecart eeprom
and partly because of the further simplifications it allows.

Also, implement low-level bit shift functions in assembly in order to get
complete control of the timings: there can be just a few cycles of slack.
Also, use the time waiting for the input line to go high to pack received
bits into bytes on-the-fly, as there is now plenty of time.

This saves about 2080 bytes of program space, and 369 bytes of global ram
space.

bea06e55fe N64.ino: Assorted low-hanging fruits 
More sizeof() use, avoiding high-level loops when a callee can do it
without the call overhead on every iteration, a bit of source code
factorisation, avoiding initializers for large variables.

d9daadb1f9 N64.ino: Build eeprom path and file name with snprintf_P 
So the format string is stored in flash rather than in ram.
The gain from doing just one like this is not much, to be done in more
places.

a43b2553cd N64.ino: Optimise controller CRC functions for speed 
Also, shave off 5 bytes from a local initializer.

d7bbc59607 N64.ino: Remove unused function 
This does not save any space as the linker noticed it wasn't used.
Also, point the (commented-out) only caller to the equivalent libc
function.

e7ef7fd4bd All: Make flashid an integer 
flashid (almost) always contains the hexadecimal representation of two
bytes, which then means it gets compares with strcmp, which in turn need
another string argument. Instead, make it an integer, removing the need to
call strcmp.
Add a separate string representation for printing purposes (maybe this can be
avoided by having the print function format it when needed ?).
The only apparent case where flashid is not an hexadecimal representation
of a pair of bytes is when N64 clears it to "CONF". Set flashid to zero
this case.
This saves about 500 bytes of program space and 200 bytes of ram.
