flate: Handle invalid block type
...
Fixes `panic: invalid enum value` when the type bits had the u2 value of 3.
Contributes towards #24741

flate change bit reader Bits to usize ( #24719 )
...
Don't see why byte returned from specialPeek needs to be shifted by
remaining_needed_bits.
I believe that decision in specialPeek should be done on the number of
the remaining bits not of the content of that bits.
Some test result are changed, but they are now consistent with the
original state as found in:

This passes tests but it doesn't provide as big a window size as is
required to decompress larger streams.
The next commit in this branch will work towards that, without
introducing an additional buffer.
