make the optitrack enabled by default in cfg

[Li-Jinjie]

If the enableOptitrack value is not explicitly set in the launch file, the package defaults to true, as specified in the source code. However, if the roscore is kept running in another terminal without restarting, this setting only takes effect once. The solution is to set the default value to True in the configuration (cfg) file.

Below are some relevant log entries:

For the first run, the enableOptitrack can be set to 1 by default.
