Graw DFM-17 radiosonde support (#61)
* Initial plumbing for DFM17 (#54)

* Implementing Si4063 radio chip support for DFM17 sonde. Work in progress.

* Add an error to indicate that the code does not work yet

* Removed copyrighted docs from documentation and provided links instead (#55)

* Fix SPI bus initialization for DFM17. Trying to make Si4063 SPI communication work (in progress). Fix LED bit polarity.

* Set DFM17 clocks correctly to 24 MHz

* Still trying to fix Si4063 SPI communication, no luck

* Add clearing of SPI overrun status flag to make Si4063 comm work properly in DFM17. Not sure about the reason this is required.

* Fix bug when setting Si4063 frequency. Remove unnecessary GPS debug and delays. Add Si4063 debug printout. Find a suitable frequency offset multiplier to achieve 270 Hz tone spacing for Horus 4FSK.

* Add some known good Si4063 configuration values. Implement direct GPIO-based modulation for Si4063 that allows support for CW now.

* DFM-17 APRS work (#60)

* Modify for APRS on DFM17

* Clean up Si4063 APRS work and make APRS deviation configurable

* Add documentation for DFM-17

* Add a note about the DFM-17 connector

* More work on docs and config for DFM-17

* Docs

* Mor work on config

* Fix RS41 URL

* Added info about high-altitude balloon flights

* Fix typo

* More code cleanup

* Update authors

* Improve DFM-17 docs

* Added a timepulse routine for DFM17 and also a millis() routine.  Working toward clock calibration.

* More refinements to the HCI calibration

* Cleaned up clock calibration code and integrated into the main radio loop.  Also added APRS telemetry for calibration.

* Added logic to (hopefully) avoid over-calibration if there is an errant timepulse.

* Clean up DFM-17 clock calibration implementation and make RS41 compile properly

* Adjust README

* Add notes about DFM-17 clock calibration

* Fix typo

* Add DFM-17 note about clock calibration to the top of the README

* Text style

* Working on README

* Working on README

* Move datasheet links to main README

* Markdown styling

* Improve config file structure

* Remove unnecessary comments
