WebRTC Stack in Firefox 110 changed, channel.js needs changes - suggesting FIX

[schlypel]

In channel.js are 2 lines, that differentiate between encoding and parameter handling for firefox vs. other browsers.

The lines are: 312 & 339
https://github.com/open-webrtc-toolkit/owt-client-javascript/blob/main/src/sdk/conference/channel.js#L312
https://github.com/open-webrtc-toolkit/owt-client-javascript/blob/main/src/sdk/conference/channel.js#L339

This breaks functionality in Firefox 110 (update was released on Feb. 14 2023)

We fixed the issue by checking not only if it is Firefox via Utils.isFirefox() but also checking if the major version is < 110.

We have the major version in our app from some other source, owt client could use Utils.sysInfo().runtime.version.

The specific handling for Firefox seems to be not longer needed in this lines.
For us it works again now.

Untested FIX:
312| if (Utils.isFirefox() && Utils.sysInfo().runtime.version.split('.')[0] < 110) {
