2022-05-04 2.5.0:
-------------------
* add calculating of canonical Huffman codes 'util.canonical_huffman()'
and decoding thereof 'util.canonical_decode()', see #173
* allow creating "Huffman codes" from frequency maps with a single symbol
in 'util.huffman_code()' and 'util.canonical_huffman()', see #172
* allow bytes-like argument in '.frombytes()' and '.pack()' - previously,
the arguments were limited to the 'bytes' object, see #174
* allow bytes-like arguments in 'util.deserialize()'
* add official pyodide support
* add [DEFLATE decompression](../examples/puff/) example
* optimize '.bytereverse()'
* optimize 'delslice()' for cases like 'del a[1:17:2]' when 'a' is large
* fix 'examples/huffman/compress.py' to handle files with 0 or 1 characters,
see also #172
* add 'skipIF' decorator for skipping tests
* add test
