Intel implementation uses a different polynomial (CRC-32/ISCSI or CRC32-C (Castagnoli)) so I had to remove the support.

Major improved of zippy format

See merge request !54

Uses hardware acceleration if available, otherwise falls back to software implementation.

Includes strong header which includes CRC32.

Also simplified error to string conversion.

This approach avoids many of the possible panics.

It's used because of static size nature of it.

Support for BOSC (Boytacean Save Compressed) format

See merge request !53

Created automatic inference of format from magic number.
Extracts BOS data from BOSC files to be used in web.

Moved BOSC up in the file for better readability.

Marks the initial step towards a compressed file format.

CPU debug information and MMU non mutable read support

See merge request !51

Made read MMU a non mutable operation.
Added support for CPU description.
Added Display support for CPU.
Extracted type definition for `Instruction`.
Support for diag_gb!() - uses global unsafe approach, which is not problematic for the purpose.
Inline fetch() operation in cpu clock.
Moved pedantic validation up in the CPU.
Fix simple diag issue.
Changed naming of read and write unsafe ops to raw.
New pedantic asserts.
Fix an issue with HDMA destination address prevent CHIP-8 ROM from
working.

Support for address ranges in match operations

See merge request !52

Uses simple ranges for matching, optimization done via LLVM.
Faster performance in read and write on x86-64.
Improved code readability.

Compression support in commons

See merge request !50

Includes simple example in main gb.rs file.
