Add option to synchronize videos on import

[philipqueen]

This PR is to add an option to the Import Videos" wizard that will run the imported videos through the SkellySynchronize` code that will synchronize them by cross corrolating their audio streams and clipping them so they are synchronized and have the exact same number of frames.

We'll know it works when a user can load freemocap select 'import videos' and load in a folder full of (say) GoPro videos that get synchronized and saved to a sycnhronzied_videos folder to be processed just like any other freemocap recording.

Tasks to be done for this to work :

freemocap side

• add a synchronize videos by their audio track checkbox (or parameter tree?) or a paramter tree pops up after they click "import" if that button is checked?) to the Import Videos wizard.

SkellySynchronize side

• save out some kind of diagnostic information to a TOML
• OPTIONAL - Make some kind of visual debug output so that we can check quality
• OPTIONAL - - Run via parameter tree model (for now just run with default values)
• OPTIONAL - fix the phone video resoultion bug (but focus on GoPro) - mostly fixed, will sometimes flip a vertical video upside down

skelly_synchronize repo: https://github.com/freemocap/skelly_synchronize
this would close #385

I've added a checkbox to synchronize videos, and added a handling function that just prints whether the button is checked or not to verify if it works.

I tried adding another page, but what we're calling a "wizard" is actually just a QDialog, and I haven't found anything on adding another page to a QDialog. I tried making it a real wizard, but ran into the trouble of dealing with the click connect on line 448 in freemocap_main_window.py when the function its connecting to is inside a WizardPage instead of a Wizard.

The takeaway is we either need to put some work into making a real wizard, or I can add all of the synchronize options onto the main window. Currently there aren't really options, so I can just have it run skelly synchronize on the folder when you click continue

I added some additional widgets that open when you click on the synchronize box, which I think is the right option for dealing with the synchronization parameters.

Also, I thought my last post mentioned this but if the synchronization button is clicked, it will run skelly synchronize on the videos before importing them, so this PR is minimally viable

I've changed the layout by putting all of the synchronization information in an hbox. Let me know @jonmatthis if there are any other aesthetic changes to make. (Ignore the coloring, I'm using changes from the recoloring PR because the dialog currently doesn't show up on my computer without them)

I've also added proper error handling to skelly_synchronize if videos don't have an audio file.

[philipqueen]

Skelly_synchronize now outputs a debug plot.

Because opencv's videowriter does not support audio, the synchronized videos do not have audio files. So what is being displayed in the "After Cross Correlation" section is the audio files from the raw videos trimmed according to the same process as the videos. This isn't ideal, but it's better than no debug, and there are checks to make sure the videos are trimmed properly.

As of today this is non-blocking (runs the synchronization in a thread) and it prints the logging messages from skelly_synchronize in the console.

I got this to work successfully on two long GoPro videos, as seen below:

Woo!
