Shank IDL's Not Parsable

[bonedaddy]

Overview

Shank idl parsing doesn't appear to be supported. Running the example below fails due to unknown field types. The IDL was downloaded from https://github.com/metaplex-foundation/mpl-token-metadata/tree/main/idls.

Error appears to be coming from

reverse-idl-parser/src/parse_idl.rs

Lines 467 to 469 in f296faa

	_ => {
	return Err("Unknown field type".into());
	}

More specifically issue appears to be because the idl is using hashMap types which aren't currently supported

Error message

Example

I'm embedded IDL's into rust binaries using lazy_static and as the metaplex idl is quite large I can't include the example in this issue, however I have uploaded a gist containing the example https://gist.github.com/bonedaddy/e4ab00aee1abb5dc4cef8ea119836fd5
