Yuhsuan/inactive frame channel

[YuHsuan-Hwang]

Description

Closes CARTAvis/carta-python#103: setting the channel/stokes of inactive frames. Fixed by adjusting the criteria for requesting tiles when channel/stokes is manually changed.

Instead of only checking the active frame and its spectrally matched frames, we now check all visible frames and their spectrally matched frames. When checking the spectrally matched frames, we skip the visible frames to avoid duplicate requests.

Currently, users cannot set the channel/stokes of inactive frames through UI, but it is possible to do so using the code snippet feature or the console. For example:

// in multi-panel mode showing >= 2 frames
const file = await app.openFile("[path]", "[filename1]");
const file2 = await app.appendFile("[path]", "[filename2]");

// set inactive frame channel
file.setChannel(1);
// set inactive frame stokes
file.setStokes(1);

In this branch, the above code snippet will immediately request new tiles for the inactive frame. In the dev branch, it will request new tiles after the frame becomes active.

@acdo2002 There will be additional tile request messages with this change, so you might want to check it.

This should be fine. No regression from e2e tests.

I can confirm that the inactive image is now re-rendered immediately when the channel is changed.

[acdo2002]

Currently the ICD-RxJS are all one file to test tiles' response.
I have confirmed this PR add additional ICD message when open two frames. ICD-RxJS need add one more tile test.

Confirm that the inactive image is rendered right after the channel is changed with my test.
