* segwit_addr_net_decode - Try to decode a Bech32(m) address and detect * testnet/mainnet/regtest/signet/testnet4 * * This processes the address and returns a string if it is a Bech32 * address specified by BIP173 or Bech32m as by BIP350. The string is * set whether it is testnet/testnet4/signet ("tb"), mainnet ("bc"), * regtest ("bcrt"). It does not check witness version and program size

 *  Returns string containing the human readable segment of bech32 address
