New node, SD Png Info

[stassius]

SD Png Info lets you retrieve generation info from any PNG on disk (or upstream image) and store the parameters in attributes. Also you can write the file to the File attribute if you want.

Note, that all the attributes are string ones. You can use them as @attribute in backticks in string parameters or atof(@attribute) in int or float parameters.

This way you can reuse parameters from the old generated files. Note, that "Save text information about generation parameters as chunks to png files" parameter should be On in Automatic settings.
