Problem summary
An error occurs and a Write node is not created when exporting with a non-default colorspace in Hiero/NukeStudio.

Customer reported version
hiero.13.0v3

Customer reported platform
windows10

Steps to reproduce
1) In Hiero, open the Project settings (Project > Edit Settings) and click Color Management.
2) Ensure the aces1.1 colorspace is set.
3) Import a clip and place it on the Timeline to create a Sequence.
4) Double-click the clip on the timeline to edit the colorspace of the clip.
5) In the Properties bin, change the colorspace of the clip to compositing_linear(ACES - AcesCG).
6) Right-click the Sequence and choose Export...
7) Select the Transcode Shots DPX preset and set the Project root path.
9) Select the Transcode option and change the colorspace to compositing_linear(ACES - AcesCG).
10) Change the file type to EXR, then enable "keep nuke script" at the bottom.
11) Render the sequence and observe any errors.

Expected behavior
The sequence should render without errors and create a Write node in the Nuke script.

Actual behavior
The sequence does not render and throws an error for: b"Script 'path/to/script.nk' contains no Write nodes." or "Unable to create Write node with invalid color space: compositing_linear (ACES - ACEScg)"

Workaround
Set the correct colorspace in Preferences...>Color Management (aces1.1 in this case), then close and re-open Hiero and export again.
