Set BW = 41.7 kHz and SF = 10 for some more range

Fix handling of payload length on Tx (FSK)

Libs based on makefile setting, LoRa configurable

Configurability (#29) ...

* Initial ideas
* Better handling of 'RFM' makefile variable/preprocessor macro

Fix preprocessor warning

Adjust output power depending on modulation

Put RFM69 in default sleep mode on init

Update comments in librfm*.h

* Initial test
* Test and adjust for RFM69

Make broadcast address configurable

Fix interpreting RSSI for feedback to transmitter

Update README.md

Rename to librfm95, fix FSK Rx with response (#27) ...

- with the "shared" FSK FIFO, must first read payload and then send response :-/

Implement LoRa mode (#26) ...

* Prepare for LoRa mode
* Partial impl. of LoRa mode
- FSK mode still works :-)
* TX and RX in LoRa mode initially working
* Response from receiver to transmitter in LoRa mode
* Refactoring

RFM95 (#25) ...

- Use librfm95 instead of librfm
- Some improvements & fixes for RFM95
- Add "unblocking" timeout + minor improvements
- Let watchdog bark each 2 seconds instead of 8
  should consume only very little more power but allows to perform checks more frequently
- Slow down SPI for the breadboard wiring

Improve RSSI - output power control loop by averaging (#23)

Use radio module's timeout function instead of homebrew... (#22) ...

...which worked too but was more complicated. Simplify, simplify!
