enhancement/Show_size_of_folder_and_files

#5 issue
I created a different route for the size (/api/browse-withsize) because I don't want users to wait for the folder size. This operation takes some time.

@mifi is this code alright?

thanks for your pr. firstly there are build errors. but more importantly I think it needs to be refactored in a way so that it:

• doesn't replace the files (setCurrentDirFiles(responseWithSize.data);), but instead it should supply the sizes only. currently the code is too duplicated
• we need to be able to cancel this. so that when changing directory, the recursiev folder size check should be canceled, or else we would consume too many resources (cpu,memory). I think cancellation could happen with an AbortController that gets aborted when the http request gets aborted. and the client has to abort the request when the user navigates to a different folder. (probably also abortcontroller there)
