One sentence summary of this PR (This should go in the CHANGELOG!)
Identify button was removed from toolbar, now identify() is ran on a resource automatically when it is selected in the GUI.

Please describe the changes in your request.
When exploring resources in the OFRAK GUI, when a resource is clicked or otherwise selected, identifiers automatically run against that resource and the resource's captions and ResourceTags get updated automatically. Because of this, the "Identify" button is no longer needed.

Given that the initial issue had some concerns about this change negatively impacting the responsiveness of the GUI I decided to run some manual benchmarking. I used a RPI5 squashfs Image from openwrt. Benchmarking showed an average delay of 115ms (worst case 758.8 ms when running identify on the top level image) per resource selection to identify and update the frontend. Due to the asynchronous nature of the UI and the fact that other things (such as the hex view) also update when you select a new resource, this was not noticeable in my opinion. Additionally, OFRAK does not re-run identifiers on resources that have already been identified. If we find this delay unacceptable, I could pivot to merging the "identify" and "unpack" buttons, as mentioned in the issue.

Anyone you think should look at this, specifically?

It seems like the CI is failing because it is trying to run wget on https://www.7-zip.org/a/7z2201-linux-x64.tar.xz, but that link is dead.
See for example: test OFRAK angr and capstone components

Seems to have been fixed here: #733

I'll review that PR and probably merge soon.

Seems like CI is passing on master, and that branch should be merged into this one to get CI to pass.

I like the idea behind this change, but will have to review the code to make sure it's the ideal way to implement this.
