* Sync with the latest stable commit in `develop` branch [`LOW-PRIORITY`]
* check deviations
### Task-D
* Write `send_mac_slot_indications()` which calls the `slot_indication` in `vnf_p7.c` file [x]
* Change the `vnf_handle_timing_info()` function that calls p7 message unpack fn and initializes the sfn and slot in `vnf_p7.c` file [x]
* Change pack and unpack functions `pack_timing_info()` and `unpack_timing_info()` [x]
* Change `nfapi_timing_info_t` structure to support P7 in NR [x]
* Change packing functions to support NR P7 procedures. [x]
### Testing
* Test by running VNF on a terminal and PNF in rfsim parallely
