Bump NWjs to 0.54.1

[haslinghuis]

To keep in sync with betaflight/betaflight-configurator#2548

Bumped the ffmpeg libraries to 0.55.0 as the prebuilt libraries are not available for 0.54.1 and 0.54.0 is incomplete.

@haslinghuis Ffmpeg also need to be update to a compatible 0.55 version,and try if all video conversions works.

[asizon]

Take it as reference #487

[haslinghuis]

The ffmpeg prebuilt library for 0.55.0 is not available yet.

Sometimes the latest version is compatible with the current version, and for this reason he does not release a new version of the library.
What I want to say is that maybe library 0.54 works for nw 0.55.

[haslinghuis]

Update: there is a new release covering both 0.54.0 and 0.55.0 but not 0.54.1 and the 0.54.0 version has no linux libraries.
https://github.com/iteufel/nwjs-ffmpeg-prebuilt/releases

Created an issue here for 0.54.x nwjs-ffmpeg-prebuilt/nwjs-ffmpeg-prebuilt#116 which does not have a linux library.

There was a problem with an user letting me downgrade 0.55.0 to 0.54.1 as this is working on Apple while maintaining the Notification Center icons as mentioned here: betaflight/betaflight-configurator#2274

[haslinghuis]

Updating with nwjs-ffmpeg-prebuilt 0.55.0 seems to work.
