neither --staker-pk and --covenant-committee-pks supports 33-bytes pub keys. so I have to remove those "02" "03" prefix

else I will get

1) [btc-staker] bad pubkey byte string size (want 32, have 33)

2) [btc-staker] staker pk in tx <redacted> do not match with flag <redacted>

the second error caused us some time to figure out the cause. so it will be easier if we can just support both pk formats

or at least we should show a better error to indicate it's the format issue rather than the key doesn't match
