No job ID

[bnmajor]

This PR provides a solution for projects that may not have a previous job id associated with them (which was required in order to request further training). As an alternative, the values typically set in the initial superpixel generation step can be set in the .histomicsui_config.yaml file:

• radius: The size of superpixels generated (UI defaults to 100)
• magnification: The magnification level at which to generate the superpixels (UI defaults to 5)
• certainty: The metric used to determine the order that predictions are presented to the user (UI defaults to confidence). Options are confidence, margin, negative_entropy, or batchbald.
• feature: The feature shape. Either superpixel image data (image) or foundation model vector (vector). The UI defaults to image.

If training is requested and there is no job id and the radius, magnification, certainty, and/or feature keys are not set in the config file, you will be notified of which are missing and have the option to open the config and set the missing values.

NOTE: There is a bug around setting values in the config. Specifically, if a string value is set with single quotes (for example feature: 'image') at the end of the file and there is a new line at the end (either added manually or automatically by using the Format button) then the UI is not automatically notified of the change and will think that the value is still missing. This can be avoided by any of the following:

• not listing string values last

radius: 100                        certainty: 'confidence' 
magnification: 5                   feature: 'image'
certainty: 'confidence'     ->     radius: 100
feature: 'image'                   magnification: 5

• not using quotes around the string value

feature: 'image'     ->     feature: image

• refreshing the UI after updating the config file

When I start a new project the normal way I've been doing it, I get a job failure: SuperpixelClassification.py: error: argument --magnification: invalid parseValue value: ''
