Use of float_t in ST code prevents compiling for Arduino Pro Mini

[ab3nd]

On Ubuntu 20.04, Arduino 1.8.13, with the library installed via downloading the zip file and importing it from Sketch -> Include Library -> Import ZIP library...

The test code is basically just the initialization from the autonomous ranging example.

The error appears to be a type issue, ST's code uses float_t. If you put "typedef float float_t" in vl53l5cx_plugin_motion_indicator.h, the compile error goes away.

Thanks, I've made the change. Sorry for the delay!
