Logitech K380 bluetooth keyboard - make function keys default

I created GitHub repository for k380 configuration program.

https://github.com/jergusg/k380-function-keys-conf

I did the same steps as Mario to get sequence for k380. The code is same as Mario's, but with the sequence for k380 keyboard and k380 device ID. It outputs write: 0 were written instead of 7 on my computer, but it works anyway.

The sequences are:

const char k380_seq_fkeys_on[]  = {0x10, 0xff, 0x0b, 0x1e, 0x00, 0x00, 0x00};
const char k380_seq_fkeys_off[] = {0x10, 0xff, 0x0b, 0x1e, 0x01, 0x00, 0x00};
