Lazy Bed Regions Download

[ducku]

• Chunk metadata from the internet is no longer downloaded until region selection
• GetChunkedData now confirms tracks from a bedURL as user might've pressed Go before tracks are fetched
• Closes #353

Summary of the current process for bedURLs:

• Upon receiving a bedURL, only the bed file is fetched and bedinfo such as regions are returned
• Upon selection of a bed region, the respective tracks.json file for that chunk is fetched and tracks are loaded into the track picker if applicable
• Upon receiving a request to getChunkedData, if a bedURL is present, the tracks.json file is re-fetched(if necessary) and used instead of the given tracks from the request in case the user hit the GO button before tracks were loaded into the track picker
• getChunkedPath is called when a bed file is included in the request, downloading the remaining chunk if the bed is a URL and returning a chunk path pointing to the location of the download

Failing

config-global.mjs loaded before either config-client.js or config-server.mjs

I'm not too sure why this happens.

@ducku This is a new check I added. Since common.mjs needs the config, but since the code to load the config on the client can't be imported on the server and visa versa, and since imports can't be conditional, you need to import config-client.js before common.mjs in client code, and you need to import config-server.mjs before common.mjs in server code.

I couldn't figure out a better way to write code that needs access to the config and also needs to be portable between the client and server.
