SettingsEXR_extra_attributes modified when writing vrscene file

[GoodbyeKansas]

Hi

It appears when having ' (ticks) as you get when converting a list to str with python. Example:

>>> foobar = ["barfoo"]
>>> str(foobar)
"['barfoo']"

Then those ticks get converted to a / when writing the metadata into the exr files. This is breaking some tools we have that reads metadata.

Attached hip file produces the result. Its not a real zip just renamed hip cause we cant upload hip files.
