this file for combined flex pcb: antenna and connection between ESP32 S2 mini and tag, so it can be produced in one flex pcb.
combined file has been kinldy provided by 123tztz321 - thank you :)
- changed ESPAsyncWebServer and AsyncTCP (both not properly maintained for more than 5 years) to more recent fork with bugfixes
- fixed concurrency issues in /imgupload. Hurts the upload performance a lot, but probably that's not a real issue. Parallel uploads are now possible (still within the max 5 TCP connection limit)
- added short date format definition in language.json
- changed english date format to mm/dd
- added lightgrey (4)/darkgrey (5)/pink (6) colors in jsontemplate (uses pattern dither)
- fixed ntp init timing
- got rid of gamma correction during dithering for quality reasons
- smaller UI improvements and textual edits
- tag grouping in the interface is now sticky across sessions
- tag auto update now shows before/after version number
- separated content types for 'not configured', 'static image', 'uploaded image' and 'home assistant' (which is all the same internally, but it confused the users to always see 'static image'
- changed channel reported by the AP to the ieee801.15.4 channel instead of the WiFi channel
- added geocoding to the 'location' fields (e.g. weather forecast). Now you can choose an ambiguous location from a dropdown.
- added 'firmware update rejected' wakeup reason
- Added Signika-SB.ttf and some small bitmap fonts
- Removed calibrib50/60/80/100/120/150 bitmap fonts, as they can be better rendered using truetype. Fallback is in place to auto translate to Signika-SB.ttf with the right size in case it is still used in a json template
- Renamed confusing tag type names to 'M2 + size' and 'M3 + size'. Because the universal firmware, there is no need to tell every subtile type change apart anymore.
- added `textbox` to json templates (https://github.com/jjwbruijn/OpenEPaperLink/wiki/Json-template#paragraph-text)
- redesign of count days/hours
- redesign of RSS feed
- designed Buienradar for more tag sizes
- on a scheduled or user initiated reboot, 'REBOOTING' is sent to the error channel of the websockets just before the connection is dropped
- phased out "hwtype": [] in content_cards.json (new location is in the tagtype json, which contains a list of valid content types)
In case of problems using this commit: keep in mind the heavy caching of the tagtypes in the browser. You might still unknowingly use the old contents.
Currently, the connection to WebSockets is hardcoded to the protocol "ws://".
If the server is put behind a proxy server (like Nginx) to support "https", the connection to websockets will fail (at least in Firefox) due to insecure protocol.
This change checks the current protocol and connects to "wss" if loaded via "https", which makes it work when loaded via proxy.
