[feat] Introduce a appDataDir path

[danrot]

Describe the problem

I am building an application using Tauri in which I would like to store some data in a file on the hard drive, so I was looking into the fs module. For available paths I have found this documentation. I feel like the correct path for storing my data on a linux system would be the dataDir path. However, this path only contains the path to the folder, without a folder for the application itself as in appDir, therefore I have to handle that on my own, which is a tedious task. Additionally I think that this is so common, that it would warrant another path preset.

Describe the solution you'd like

I would like to be able to use something like BaseDirectory.AppData, that stores data in a folder for my own application within dataDir.

Alternatives considered

No alternatives other than leaving it the way it is and handle that in the application itself come to my mind.

It would be worth considering a cohesive scheme for all the different app-specific directories - for example, config, data, cache, and probably others.

I would suggest:

• appConfigDir (appDir would need to be kept as an alias for now to avoid a breaking change)
• appDataDir
• appCacheDir
• I can't think of any others but maybe there are more?

Personally I think the current appDir is confusingly named anyway because I would expect it to point to the directory where the actual app is located, rather than to a config dir.

I agree current appDir is misleading and as long as we don't introduce a breaking change, this could be a good addition in v1.2. However I think we could just introduce appConfigDir as a separate function without aliasing so it could have a documentation and would include @since tag

logDir is another one that could be renamed to appLogDir to fit with the rest

Wow, that was fast! Thank you, everybody!
