canonical timestamp

[truher]

quick question, i'm looking for the canonical way to get the current ntcore timestamp, so i can publish the correct measurement times. is it ntcore._now()? mypy complains about touching the underscored "python pretty please private" method there.

ntcore._now maps to ntcore::now (https://github.com/robotpy/mostrobotpy/blob/main/subprojects/pyntcore/gen/ntcore_cpp.yml#L16 ... https://github.com/wpilibsuite/allwpilib/blob/main/ntcore/src/main/native/include/ntcore_cpp.h#L1227)
