UDP send marker example is incorrect

[Purple-Fox-Coder]

Problem

The send marker example sends a double

msg = struct.pack('!d', marker)

Expected

The example should instead send a float, as suggested by the documentation at:
https://docs.openbci.com/Software/OpenBCISoftware/GUIWidgets/#using-udp-to-send-markers

msg = struct.pack('!f', marker)

Console Log and Screenshots

Using Synthetic streaming for testing purposes.

Using the following message over UDP as in the example:

struct.pack('!d', float(3.0))

The GUI reports

Inserted marker 2.125

When using the following message over UDP:

struct.pack('!f', float(3.0))

The GUI reports correctly:

Inserted marker 3.0
