Add a feature for exporting method invocation list

[cheesecat47]

Hello, I was impressed with the scavenger presentation at Deview 2023. So I forked this repository as I could use it for something I'm working on.
It's been helpful for me to identify all the methods in my Java project in a short time and know if they are executing or not.
However, in the current version, there was no way to export the collected information on a website (although I can query it directly from the DB). I wanted to contribute, so I added that feature.
This is my first time contributing to open source project, so it may need to be improved on many points. Any feedback would be greatly appreciated.

Here's the description of this PR.

• Added an "Export" button to the bottom of the SnapshotDetail page.
  
• Press that button to download a TSV file with the following information.

@cheesecat47 Firstly, thank you so much for your interest in scavenger :)
I'd like to know what the primary purpose of this feature is.
If it's to determine which methods are considered dead code (not invoked), I'd suggest adding a filter button next to the search bar to see only not invoked methods.
I think this would be a cool feature if it could be used in more ways than just that.

@taeyeon-Kim I appreciate your feedback!
I wanted to add this feature to compare the results of Scavenger with the results of the tool I'm using. Also, because I'm more familiar with Python, I wanted to export Scavenger results to a CSV file. However, in the current version of Scavenger, there is no way to download the information displayed on the website. That's why I tried it.
Is the reason the export button wasn't added because exporting results to a file wasn't in the use cases you expected? If so, replacing the button with the filter feature you mentioned would be better. It seems more useful to show multiple search results than I did, like showing query results in Kibana.
If it's okay to keep the button, then it would be nice to modify it to export the filtered results (the screen you're currently looking at) so you don't have to create a contextual button.

Sorry for the late comment.
First, how about moving the feature to the snapshot table page?

<!-- main.js -->
import {faFileExport} from "@fortawesome/free-solid-svg-icons";
iconRegister.add(faFileExport);


 <!--  SnapshotTable.vue-->
<el-table-column :label="'$t('message.snapshot.export')'" width="80" align="center">
    <template #default="scope">
        <el-button circle type="primary" @click="refreshSnapshot(scope.row.id)">
            <font-awesome-icon icon="fa-solid fa-file-export"/>
        </el-button>
    </template>
</el-table-column>

I would also like to see this feature changed to allow exporting per snapshot instead of for the entire invocation.

@taeyeon-Kim First, thank you for your detailed and kind comments.
May I ask how did you use features like live reloading in your development? Because building every time takes too long..
