PharoThings to Pharo 7 and Pharo 8

Improvements on ReadWriteLock, Object Statistics, and Seamless.
This version works on Pharo 7 and Pharo 8, but not in Pharo 9.
To changes at this level requires a lot of effort to keep the retro compatibility.
The main branch will be split into Pharo7, Pharo8, being the main branch supporting Pharo 9.
The fixes to work it on Pharo 9 will be done on the main branch.
This is the last tag with the master branch supporting Pharo 7/8/9.

BMP280 and MCP9808 sensors

Temperature sensors are implemented as separate classes:

• PotBMP280Device
• PotMCP9808Device

They incapsulate required initialisation logic and actual data reading:

• readTemperature (returns number in Celsius)

BMP280 is more advanced sensor. It also measures pressure and humidity. To get all parameters use #readParameters message which returns three items array (Celsius, hPa, humidity percents)

It is major stable version 0.2

Based on latest TelePharo 0.2 and Calypso 0.8
