Subject: [PATCH] Update README.md to prepare formal release (#273)

Adds PV strings 7-18 for Fox ESS R series
As the OpenAPI is performing well again, the enforced delay of 5 seconds between API calls has been reduced to 2 making startup much faster.
Fixes a bug that burnt through personal API calls if the device variable call returned an error 41200 (a Foxess internal data query error)
