What's Changed
* RC 1.2.48 by semuadmin in https://github.com/semuconsulting/pyubx2/pull/167

1. Add helper methods `val2twoscomp` and `val2signmag` to convert signed integer to appropriate two's complement or sign magnitude binary representation. Can be helpful when populating UBX ESF-MEAS `dataField` values such as speed or wheel tick, as these use both varieties of [signed integer representation](https://en.wikipedia.org/wiki/Signed_number_representations).
