Implemented Infineon TLV493D, a 3-dimensional hall effect sensor:
https://www.infineon.com/cms/en/product/sensor/magnetic-sensors/magnetic-position-sensors/3d-magnetics/tlv493d-a1b6/
This is also available through Adafruit: https://www.adafruit.com/product/4366
I tried to be comprehensive in the implementation, trying to cover use cases ranging from ultra-low-power to high frequency with low precision required.
I've not included in this PR a higher-level filter to measure an angle (typical application for this sensor, see https://www.infineon.com/dgdl/Infineon-3D_Magnetic_Sensor_for_Angle_Measurements-AN-v01_10-AN-v01_01-EN.pdf?fileId=5546d46265f064ff01665a3d22f055e3) - I didn't include it as I think it's beyond the scope of periph.io, and it's full of floats. Is there any interest in such thing?
Also, I'll try to add that in the documentation (as well as the long overdue ADS1x15... sorry for that)
Thanks!
Benjamin
