Restructuring of code, **update to v7.22.5 first**

What's Changed

Predbat is now split into multiple files

Note: To update to v8.0.0 from inside Predbat you must update to v7.22.5 first. HACS updates are not impacted.

• Complete Predbat split by @springfall2008 in #1195
• Added emergency downloader for missing files by @springfall2008 in #1197

User settings are now saved in a file

The user config options are now saved in predbat_config.json automatically and restored on restart. This is largely to prevent issues
where HA loses some settings

• Save and restore settings from file rather than just using HA storage by @springfall2008 in #1200

Bug fixes

• Fix bug where pause mode is not cleared correctly on discharge by @springfall2008 in #1201

• Fix to reading of incrementing load by @springfall2008 in #1205
