aspect ratio for dim's; sliders adjust by ratio

Browse source 
Default choices added to settings in user interface section
Choices are editable by user

User selects from dropdown.
When you move one slider, the other adjusts according to the ratio
chosen.
Vice versa for the other slider.

Number fields for changes work as well.

For disabling ratio, an unlock pad "🔓" is available as a default.
This string can be changed to anything to serve as a disable,
as long as there is no colon ":".

Ratios are entered in this format, floats or ints with a colon "1:1".
The string is split at the colon, parses left and right as floats to
perform the math.

/* This is a basic library that allows controlling elements that take some form of user input.
This was previously written in typescript, where all controllers implemented an interface. Not
all methods were needed in all the controllers, but it was done to keep a common interface, so
your main app can serve as a controller of controllers.
These controllers were built to work on the shapes of html elements that gradio components use.
There may be some notes in it that only applied to my use case, but I left them to help others
along.
You will need the parent element for these to work.
The parent element can be defined as the element (div) that gets the element id when assigning
an element id to a gradio component.
Example:
gr.TextBox(value="...", elem_id="THISID")
Basic usage, grab an element that is the parent container for the component.
Send it in to the class, like a function, don't forget the "new" keyword so it calls the constructor
and sends back a new object.
Example:
let txt2imgPrompt = new TextComponentController(gradioApp().querySelector("#txt2img_prompt"))
Then use the getVal() method to get the value, or use the setVal(myValue) method to set the value.
Input types that are groups, like Checkbox groups (not individual checkboxes), take in an array of values.
Checkbox group has to reset all values to False (unchecked), then set the values in your array to true (checked).
If you don't hold a reference to the values (the labels in string format), you can acquire them using the getVal() method.
