Release 1.01 of the library

Minor issue with build scripts has been fixed.

Release 1.0 of the library

Change list:

• pico-hf-library changed to v.1.0
• max working frequency shifted from 9.4 MHz to 32.333 MHz

Please notice that frequency stability of standalone Pico (w/o GPS) may be insufficient to work WSPR on 10+ MHz bands.

Release 0.51 of the Raspberry Pi Pico WSPR beacon

There are serious improvements:

• GPS receiver (GPRMC & PPS output) support has been added. The GPS receiver is used to schedule WSPR tx sessions as well as to compensate Pico's frequency drift. As result, now you hold a complete solution to build up a WSPR beacon which boasts of high frequency stability (0.5 ppm or better) in vast temperature range.

• the TX scheduler. It holds two minute WSPR tx slots and supports configuring % of slots we use to tx.
