New FW release
Version v1.1-88

Changes:
- The spurs caused by the 48MHz MCU clock have been reduced.
- The scanraw command progress is displayed using the green progress bar.

tinySA-App uses the scanraw command and with a large number of points and a low RBW it often is not obvious if the tinySA is still? scanning or how long? it would take till the end of the scan. The green progress bar give better insight in scanraw progress.

The mechanism used to reduce the MCU spurs makes some assumptions which I would like to see verified by some users.
Can some of you test this using the console command:
selftest 6
In reply you get a list of frequencies.
I'm interested in the frequencies listed after 12 to 20
This is what I get.
12:? ?94.602M
13:? ?94.989M
14:? ?95.377M
15:? ?95.764M
16:? ?96.069M
17:? ?96.456M
18:? ?96.844M
19:? ?97.231M
20:? ?97.536M
