Subject: [PATCH] Fix JSON.Parser to have an explicit error type.

Prior to this commit, the library wasn't compiling with the latest
version of Savi because latest Savi allows for error values with
a designated type, but this function was self-recursive and thus
couldn't confidently infer the error type.

This commit resolves the ambiguity by adding `:errors None`.
