[EXPERIMENTAL] Argo WREM2 - changed proto msg size: 96->90 bits

[mbronk]

Includes matchBytes() change to be able to work with non-byte-aligned bit lengths.

Status: EXPERIMENTAL

Based off #2133 captures and the fact the last 6 bits were unused/past checksum, looks like true proto length may be 90-bit (vs. previous value of 96), hence the adjustment. I do NOT own any WREM2 device so unable to tell if this violates any backwards compatibility and whether the captures in #2133 are the WREM2 or if there's a 96-bit variant out there as well.
