Temp workaround for SIG_WA deserialize error - breaks indexing on parser 2.1

[bensig]

Hopefully this helps someone who is facing the same issue, and or the EOSRIO team is able to patch something

NOTE: This seems to be fixed in the latest https://github.com/EOSIO/eosjs/blob/v22.1.0/src/eosjs-numeric.ts - but that doesn't match the code in addons/eosjs-native

Nodeos version: 2.1
Parser version: 2.1

Ran into an error synchronizing blocks signed with SIG_WA_ - here are 2 examples:
79955656
79996963

Would cause my indexer to kick into constant complaint mode about a missing block:

The end of this logfile would just continue to have the same "Missing block" error forever and would not write many blocks to the queue...

I was able to patch the file addons/eosjs-native/eosjs-numeric.jswith an update to translate the WA keytype.

Now I am able to completely synchronize the range, even though I am seeing this new error in the pm2 out:

Nothing shows in the deserialization error logs for these errors.
