feat: add upgrade command to support self upgrade (#239)

[yanecc]

I have implemented the Windows part based on @ankit-pn's work at #38 and resolved the conflicts, it is now able to work as expected, namely upgrade to the latest version 0.4.1.

Is it possible to introduce some third-party libraries or refer to the implementation of third-party libraries to complete this function?

This go version management tool supports self-update, and everything works fine when I use it under window.

I don't like to introduce too many third party packages.

can refer to related implementations
just wanted to get some inspiration from these libraries

There is an issue. We need to ask for administrator privileges when upgrading for vfox installed by setup, which is currently not handled by this change.

I've fixed the issue, but I don't have write access to your repository, so I can't commit at the moment.

I have invited you as collaborator. Here is my repo.

I have tested it on Windows.

I have diligently read about the libraries related to self-update, and the tool you mentioned just relies on one of them (voidint/go-update).
For self-update on Windows, there are roughly two types.
The most common is to hide the old executable.

sanbornm/go-selfupdate
voidint/go-update
minio/selfupdate
inconshreveable/go-update
555f/selfupdate
starudream/go-lib

(The above is completely the same.)
Another way is to insert a randomness in the name to mitigate it.

artpar/rclone

I would prefer the current handling method, which actually removes the old executable with the cmd tool of Windows itself.
