Functions
Segment a bech32 address into its hrp and encoding values
Creates a Bech32 address, which is starting by bc1, out of an Extended Public Key
Creates a Bech32 address, which is starting by bc1, out of a 160 bits public key hash
Creates either of these Bech32 native address types
Applies the address's checksum to make sure it's valid
