#### ANGLE_DEBUG_READ
`ANGLE_DEBUG_READ CHIP=<config_name> REG=<register>`: Queries sensor
register "register" (e.g. 44 or 0x2C). Can be useful for debugging
purposes. This is only available for tle5012b chips.
#### ANGLE_DEBUG_WRITE
`ANGLE_DEBUG_WRITE CHIP=<config_name> REG=<register> VAL=<value>`:
Writes raw "value" into register "register". Both "value" and
"register" can be a decimal or a hexadecimal integer. Use with care,
and refer to sensor data sheet for the reference. This is only
available for tle5012b chips.
