Get-DFSR-Schedules.ps1

What this crap does:
Get the DFS-R replication schedule for replication groups in a specified domain. Highlight green if custom schedule
is applied, highlight yellow if schedule is full-time-no-throttle and highlight red if schedule does not fit either.
### The 'BandwidthDetail' property of the 'Get-DfsrGroupSchedule' object is in a single string format. Each hexadecimal
digit represents a 15 minute block of time that begins with Sunday morning at 12am and ends on Saturday night at 11:59pm.
The hexadecimal codes translate as follows:
0 = no replication
1 = 16 Kbps
2 = 64 Kbps
3 = 128 Kbps
4 = 256 Kbps
5 = 512 Kbps
6 = 1 Mbps
7 = 2 Mbps
8 = 4 Mbps
9 = 8 Mbps
A = 16 Mbps
B = 32 Mbps
C = 64 Mbps
D = 128 Mbps
E = 256 Mbps
F = Full; no throttle
