MATEKF722 - ESC's don't arm since build 1613

[loomerco]

Describe the bug MATEKF722 - ESC's don't arm since build 1613 (and up to 1615 as of today its the last).

To Reproduce use above build with BLHELI32 rev 32.36 (inverted DSHOT)

Expected behavior In builds 1604-1612 unsing the same config ESC's arm, only there are dual startup tones.

Setup / Versions

• MATEKF722. original.
• ESC's: DYS aria32. Firmware: Test ver 32.63 (inverted DSHOT).

Do your escs arm if you switch off dshot_bidir, @loomerco ?

Updating: just went checking your request @joelucid and found out that today everything works fine, whilst yesterday this was totally consistent multiple flashing back and forth between the versions (with full erase). I even tried the same sequence of flashing I did yesterday and it works as well. so this can be closed for now.
