Bypass "docs" in anchor idl generation

Issue:
From issue bmresearch#22, generating code from an anchor idl which contains a docs element such as "docs":[ "String" ] will crash the code when executed.
Solution:
These lines of code will be able to look at the docs section without issue, however these changes do not generate code with the contents of docs.
