Pypowerwall

* PyPI 0.6.0
* Added HTTP persistent connections for API requests to Powerwall Gateway by mcbirse in https://github.com/jasonacox/pypowerwall/pull/21
* Requests to Gateway will now re-use persistent http connections which reduces load and increases response time.
* Uses default connection `poolmaxsize=10` to align with Session object defaults. Note: pool use applies to multi-threaded use of pyPowerwall only, e.g. as with the pyPowerwall Proxy Server.
* Added env `PW_POOL_MAXSIZE` to proxy server to allow this to be controlled (persistent connections disabled if set to zero).
* Added env `PW_TIMEOUT` to proxy server to allow timeout on requests to be adjusted.

* PyPI 0.5.1
* Add FreeBSD-specific installation instructions by zi0r in https://github.com/jasonacox/pypowerwall/pull/18
* Add `grid_status()` responses for syncing to off-grid by mcbirse in https://github.com/jasonacox/pypowerwall/pull/19

* PyPI 0.5.0
* Added additional exception handling to help identify connection and login errors.
* Added `is_connected()` function to test for a successful connection to the Powerwall.
* Added firmware version to command line network scan (`python -m pypowerwall scan`)

[Proxy Server](https://github.com/jasonacox/pypowerwall/tree/main/proxy#pypowerwall-proxy-server) Updates (Build t16) - See [here](https://github.com/jasonacox/pypowerwall/blob/main/proxy/HELP.md#release-notes) for more Proxy Release notes.
