Python-fmrest

* Configure proxies for auth requests made to Cognito
* Configure proxies for FileMaker Cloud Data API

Note: when configuring a proxy and you're not just using it for local debugging (e.g. a local interception proxy), always make sure you trust the proxy server and use a secure connection.

Thanks TDKorn for the PR!

* Proxy support
* Added examples
* Configurable API versions
* Support for metadata routes

Thanks to contributor DonPasquale

Added support for Claris Cloud logins (thanks marklivolsi)

Added support for automatically trying to get a new token when FMS returns an invalid token error (952) for a request (set `auto_relogin` on the `Server` instance to True if you want to use the feature). Disabled by default to keep backward compatibility.

This version adds functionality to access the dataInfo section of a FMS response. You can access it "as is" via the `info` property of any `Foundset` instance (includes portal foundsets). (Also see: https://github.com/davidhamann/python-fmrest/issues/12)

* Fixed installation issue when preferred encoding was not set to utf-8.
