Support for BMP390L

[generationmake]

The BMP390L is the successor of the BMP388 and has better performance.

The BMP390L is pin- and register-compatible to the BMP388. Anyway we should check if it also works with this library and update the documentation. It also has few additional registers and config bits.

Hi @generationmake 👋 ☕
That's an excellent idea. Could you set-up one of your NavShieldBNO boards with a BMP390L for testing? I don't think it would be to difficult to adjust the code to support the upgraded barometric pressure sensor.
