Sequence count likely not coming from header

[skliper]

Describe the bug
Looks like sequence count as displayed on the telemetry subsystem pages is not the sequence count from the header

To Reproduce
Steps to reproduce the behavior:

1. Start cFE, start cFS-GroundStation, open cmd and tlm pages
2. Send enable tlm command to 127.0.0.1
3. Wait for packet counter to increment (> 1)
4. Open ES subsystem page, sequence count will start at 1 and increment (should start higher since packets have been received)
5. Close ES subsystem page, reopen and sequence count will start at 1 again

Expected behavior
Sequence count should be coming from the packet header, wouldn't restart every time the page opens.

I have discovered the source of this issue, but it might take me a bit to come with a good solution.
