gNB PHY-TEST: Introduced --Dmod/Umod option for scheduling slot >= 64 in FR2-FDD case

Browse Source 
--Dmod option/--Umod option,
for example --Dmod 1 will schedule every slot in slots per frame
--Dmod 3 will schedule every 3rd slot. You can use --Dmod option togethor with -D option
same for uplink scheduling too.

for FR2 with 120Khz scs, there are 80 slots. Removed the assert such that FR2 config
can be tested in phy-test, currently bitmap works only until 64 slots.
