81f0af3cf2 Fixes humidity factor & removes illumminance 
The reason for removing illuminance is to leave enough space for the
full name AD element "prst". There may be options for also sending the
illuminance (extended adv, scan response etc), with different power
consumption/overhead/complexity tradeoffs. For now let's keep it simple.

ce4c496f4d Uses newly minted 0x14 sensor type for moisture 
I also comment out the illiminance sensor, since we need the space for
encoding the device's name - "prst".

6ea0bb8525 First stab at an alternative, BTHome compatible BLE protocol 
This protococol (https://bthome.io/) allows for automatic sensor
detection in Home Assistant, as long as the device broadcasts its
sensors in the expected format.

a7732f106b Introduces new config flag PRST_BLE_EXPERIMENTAL_LONG_RANGE 
This flags makes use of the Coded PHY from Bluetooth 5. It should be
treated as an experimental feature and it's disabled by default.
Note that clients (such as ESPHomme) would also have to scan on the
Coded PHY to be able to find b-parasites operating in this mode.
Currently, no client does that. Thus the feature is disabled and marked
as experimental.

e7f7f96797 Moves KiCad project file to KiCad 6 
Moved the Q4 photodiode footprint dot (representing the collector) so
it's more clearly visible. Hopefully it will help addressing the
recurring confusion about Q4's orientation (#3, #42).

8fd4d7222a Implements BLE protocol v2 
The only change from v1 is how the temperature is encoded. In v2, two
bytes at offset 4 and 5  represent a 16-bit signed int (in big-endian).
It contains the temperature in degrees Celsius *  100.

Adds photoresistor

This PR introduces a photoresistor (LDR) on the board. The code has also been updated for sampling the LDR, estimating the illuminance in lux and encoding that value in the BLE payload.
