Domain-type validation for fee granter option

[adizere]

I document the config.toml option in 16fc6a2 but left that segment of the configuration file commented-out. The reason for keeping this option a bit hidden is that it may be a source of misconfiguration. In particular, we don't validate the string in any way, and I suspect it should be a bech32-valid account identifier, but unclear how (if) we can validate that on Hermes side.

Currently, using a random string such as fee_granter = 'adi' will yield a very obscure error message (see below). Will open an issue to track this.

Error message when using invalid fee granter account

as example tmkms trust bench32 in user-config:
https://github.com/iqlusioninc/tmkms/blob/e50ebcb75c554ac7dd8da6df6450ae75eb86f50a/src/tx_signer.rs#L97

if the user entered the wrong bench32 sdk will return errors
