Implementing personal settings to use local sd-models

[lengthtail]

I believe that there are many users who would like to try FRESCO along with their locally stored models more easily.
Therefore, I made a simple implementation so that the paths of local models can be saved and used in personal_settings.yaml.

In this implementation, I worked on the following

• personal_settings.yaml is generated by initial load.
• From the web UI, the path of the directory where the local model / VAE is stored can be saved in personal_settings.yaml.
• The output directory of the generated results can also be specified.
• In the original implementation of FRESCO's webUI.py, blend.mp4 and the generated results are overwritten each time they are generated (because the file / directory name is constant). For users who want to avoid this, I added a setting that allows incremental naming directory and blend.mp4 file name.

I have made several more changes to the FRESCO code I'm locally using.
So there may be some bugs as I made this pull request with only these features cut out.
In that case, I am sorry, but please point it out to me.

Please consider incorporating it into the main branch!

P.S. This modified version seems to work fine in my local environment.
However, when I loaded the local model for the first time, I got an error message in the CLI, so I followed the recommendation and installed omegaconf additionally.
I have not been able to verify in detail why that was necessary, but others may need that as well.
