BIP173 specifically calls out that encoders must always output an all lowercase bech32 string and that the lowercase form is used when determining a character's value for calculating the checksum. Currently, the implementation does not respect either of those requirements. This modifies the Encode function to convert the provided HRP to lowercase to ensure the requirements are satisfied and adds tests accordingly.
