These changes make shank generated IDL closer to Anchor format. Additionally, it renames the default_optional_accounts tag to legacy_optional_accounts_strategy. With this change, the default behaviour is to replace missing optional accounts with the program id, unless the legacy_optional_accounts_strategy attribute is used.
Finally, it includes a new attribute on the account annotation: optional_signer. This can be use instead of signer to indicate that the account is an optional signer. When optional_signer is given, isSigner will be set to false on the IDL and a new isOptionalSigner attribute will be set to true.
