Pyspartn

What's Changed
* Rc 0.4.0 by semuadmin in https://github.com/semuconsulting/pyspartn/pull/24
FIXES:

1. Fix `TypeError: can't subtract offset-naive and offset-aware datetimes` error when using default basedates. Basedates must always contain timezone information.
1. Use `timezone.utc` rather than `datetime.UTC` for compatibility with older Python versions.

What's Changed
* Release candidate 0.3.3 beta by semuadmin in https://github.com/semuconsulting/pyspartn/pull/22

1. Update handling of SPARTN-1X-BPAC and SPARTN-1X-EAS-DYN message types (not yet tested).
1. Add improved handling of half-day rollovers when decrypting SPARTN datastreams - thanks to JonathanMullerGeosatis for contribution:

What's Changed
* Release Candidate 0.3.2-beta by semuadmin in https://github.com/semuconsulting/pyspartn/pull/19

ENHANCEMENTS:

Thanks to jonathanmuller for contributions.

1. Attributes are now converted to type automatically e.g. float attributes will automatically be converted to floats via the enc2float() helper method using the documented resolution and range minimum values.
1. SPARTNReader will now store any 32-bit gnssTimeTags for each msgSubtype (GPS, GLO, GAL, etc.) from the incoming datastream for use as 'basedates' in the decryption of any encrypted messages with ambiguous 16-bit gnssTimetags (timeTagtype = 0). If no 32-bit gnssTimeTags are available for a given msgSubtype, the input argument 'basedate' will be used instead, adjusted for any UTC & leap second shift for that msgSubtype (e.g. GLONASS basedate = GPS + 3600*3-18).
1. Add enumerations in spartntables.py.
1. Update test cases.
1. Other minor internal streamlining.

FIXES:

1. Fix datadesc() helper method with certain attribute names e.g. SF049a.

What's Changed
* Rc 0.3.1 beta by semuadmin in https://github.com/semuconsulting/pyspartn/pull/18

FIXES:

1. Fix Area count iterations - attribute `SF030` represents (area count - 1). Affects GAD and HPAC payloads - if you're iterating through area groups, remember to use a range of `SF030+1` rather than `SF030` (see, for example, [gad_plot.py](https://github.com/semuconsulting/pyspartn/blob/main/examples/gad_plot.py)).

ENHANCEMENTS:

1. Examples updated.

What's Changed
* RELEASE CANDIDATE 0.3.0 beta by semuadmin in https://github.com/semuconsulting/pyspartn/pull/15

ENHANCEMENTS:

1. Streamline and simplify conditional group parsing.
1. Enable decrypt for all OCB messages (not just where nData > 35).
1. Update development status to 'Beta'.
1. Additional examples added for SPARTN MQTT client processing.

FIXES:

1. Fix OCB IODE payload definition - thanks to jonathanmuller for contribution.
