[ENGINE] Changed nomenclature (from motor to engine) inside src folder, except in rigv2 and mavlink messages.

[ENGINE] Changed nomenclature (from motor to engine) inside src/Engine folder and within the log decoder.

[ENGINE][WIP] Begun nomenclature refactoring: transitioning from motor to engine. Changed folder and file names.

* Added Main and Engine Orion BSPs
* Updated RIGv2 GSE_TM Mavlink message
* Added ND015X driver
* Updated VN100 serial driver

Apparently there still are top and bottom pressures for the OX tank...

The second load cell on the RIG now measures the rocket mass. The OX tank weight measurement is derived by applying an offset to the rocket mass.
The load cell has also been properly calibrated.

`rig-v-adc-test` prints ADC values for all channels to serial output, mainly used for shunt resistance testing. The voltage printed is averaged over time with a moving average.

* Re-measured shunt resistance for new and old ADC channels
* Updated trafag ranges for the next cold flow test

We have a ridicolously low bitrate :'(

The N2 3-way valve requires special handling as it's not included in the servos list,
because of it not requiring to be atomic.

Less annoying, still as useful as before. You're expected to read full telemetry from a PC anyway...

* Add missing pressure transducers initialization
* Improve failure reporting
* Add ADC specific enable flags

Updated pressure transducers list for the Orion system:
* OX Vessel
* OX Filling
* N2 Vessel 1
* N2 Vessel 2
* N2 Filling
* OX Tank Top
* OX Tank Bottom

Boardcore has also been updated to include the updated BSP enabling up to 12 servos.

PT_1: 100 bar
PT_2: 250 bar
PT_3: 100 bar
PT_4: 250 bar

Methods in the Sensors class have NOT been updated yet, which means their name is mismatching with the pressure they sample, but they sample correct data.
The mavlink message contains the correct name of the pressure value. This will be fixed in the future.
