Ditching SPIFFS

I am happy to announce that i am finally ditching SPIFFS over PROGMEM for serving Webpage Files.
First of all, It was a total disaster for beginners to understand it properly and upload accordingly. Secondly, SPIFFS required to be re-uploaded whenever a new version of ESP-DASH was released. Therefore, To overcome this caveat:

I created a special JS Script which converts the built Vuejs Webpage to a Gzipped Byte array for arduino. It makes it super easy for new updates from now on. You will only have to upload your same code once and webpage will also get updated along with it. No burden of uploading SPIFFS again!.

Changes:

• Updated and cleaned up Vuejs Code 💼
• Ditched SPIFFS for PROGMEM, Now Webpages will be served by reading PROGMEM 📝
• Made About page less disturbing 😜
• Added New Gauge Chart! 🎉
• Edited Fading Animation to end in 0.3s. Webpage should feel faster now.

That's All. Use, Like and Star Gaze the repo 🌟 !

v2.1.4

Incremented Library Version for Next Release

v2.1.3

Update library.json

Updated library.properties

v2.1.2

Update library.properties

Fixed Line Chart JSON Memory Allocation

• Increased JSON Memory for Line Charts
• Fixed where JSON memory allocated for (Int) Line Chart was 250 rather than 1000

Fixed Webpage not loading on WebKit (Apple) Devices

• Fixed Gzip Problem which lead to page not loading on apple devices. ( app.js.gz didn't work, renaming to app.js with compression enabled made it work. Apple's safari (webkit) is weird we gotta accept it. )
• Fixed couple of C++ Mistakes
• Allocated more JSON memory to update function of LineChart.

REQUIRED: You need to re-upload SPIFFS and code with latest ESP-DASH Release to apply the fixes.

Thanks to @billinsd and @windynips for reporting the errors.

Added Access Point Examples

Try ESP-DASH in access point mode without connecting to your router!

Added ESP8266_AP and ESP32_AP Example Sketches.

Compatible with Arduino JSON v2.8.0

ArduinoJson v6.8.0 introduced some breaking changes. Therefore modified library according to it's new syntax.
