V1.5: Over The Air Updates

I've added OTA updating to the code, and a mechanism so that you can name the device.
See mywifi.sample.h to control this.
I've also removed all WiFi power saving, since it can dull response times to requests.

Better browser support

Fixes display issues with FireFox and possibly others.

v1.3 - 2021 refresh

A roundup release; rebuilt and tested with the latest versions of ESP Arduino core, Sparkfun sensor lib and ArduinoJSON

The README has been updated with some better notes on constructing and programming the unit.

I also fixed a silly bug in the compile, and now run travis builds on the code both with, and without custom WiFi config to catch errors like this in future.

Finally; the scadfile for the frame is updated and made easier to customise.

Published Version

Some minor updates to the timeout handling. This is the package I intend to upload to Hackaday.

Reducing Network lag

Moved from using alternating (synchronous(==bad)) requests for reading to a model using a single request and handler, running asynchronously.

• This has considerably improved scan/reading speed and made scan movement much smoother.
• The UI can still be a bit laggy, sorry.

Simple Lidar

Working well, as described in README etc.
Designated a release point.

Initial, good enough for a pleasing demo

Works well within it's limits; several of which are driver licence imposed.
