Release 1.29.2

This is a feature release for ethdo. Changes include:

• fix regression where validator index could not be used as an account specifier
• allow use of keystores with validator credentials set
• tidy up various command options to provide more standard usage
• add mainnet fallback beacon node

Note that because some command options have been renamed it is possible that this can cause problems with scripts that use these commands. If you use ethdo in your scripts please check the command options for the commands you use with ethdo <command> --help to see if any options have changed.
