BIP-0350: use bech32m for witness version 1+ addresses
...
We have supported sending to any witness version since Electrum 3.0, using
addresses as specified in BIP-0173 (bech32 encoding).
BIP-0350 makes a breaking change in address encoding, and recommends using
(and using only) a new encoding (bech32m) for sending to witness version 1
and later. The address encoding for currently in use witness v0 addresses
remains the same, as in BIP-0173; following the BIP-0350 spec.

bech32: another around 10% speedup for bech32_decode
...
turns out stdlib ord() is somewhat slow;
also, only lookup data chars once
benchmarked with:
```

from electrum.segwit_addr import bech32_decode
electrum.constants.set_testnet()
