Parser doesn't handle circular dependencies

[sicklydove]

Thrift includes support for circular dependencies - although the python thrift generation doesn't yet support this feature. When trying to load thrift files with cyclic dependencies, the parser bombs out with a thriftpy.parser.exc.ThriftParserError e.g:

struct TFoo {
  1. required string a_string, 
  2: optional TBar bar,
}

struct TBar {
  1: required i32 some_id,
  2: required TFoo foo,
}

It's a known defect, thanks for reporting, I will try to fix it in the future.

I tried to fix it in thriftpy2, go to Thriftpy/thriftpy2#21 and get more informations, hope to see your feedback, thanks.
