Other information

[xelaint]

The radioset component name should be updated to radio-set

DaffRadiosetModule -> DaffRadioSetModule
DaffRadiosetComponent -> DaffRadioSetComponent

The radio files are named incorrectly? should be radio.component.html, radio.component.scss, radio.component.spec.ts

@damienwebdev Should I do the style updates in the same PR or branch off?

Can you also update the radio-set file names accordingly?
