Beta 7 (beta6 skipped)v1.b7

- API: change memory allocation for payload, they are now part of the struct for TX/RX, no need to malloc/free
- reduced number of SPI transactions to fetch a packet (improved number a packets par second that can be downloaded from gateway)
- streamlined build process, main target is now a static library: libloragw.a
- All RX chains can use any of the two radios now
- FSK is available and working in TX and RX (variable length mode)
- Calibrated RSSI for FSK
- lgw_connect now check the CHIP_ID
- Added a license file and a changelog
- Added a function returning a version string to allow identification of the version/options once compiled
