Add destinationPath option

[drag0s]

If this option is specified, it would allow a user to choose video's destination path. Else, destination path would still be the path generated by tempy.

What's your use-case for this?

[sindresorhus]

It should be noted that it's better to not set this and rather move the file when the export is done, so users don't see a incomplete file during recording.

Or set this to a temp directory on a different disk if it's set for space reasons.

I know this PR is already a bit older however I, too, would be interested in this addition.
I can't speak for anyone else of course but my personal use case for this is relatively simple: My main drive is quite small and already occupied by other vital stuff. Not being able to change where the original recording saves to is a major hindrance when you only have very little space left.
Meanwhile I have an entirely unused 1TB SSD mounted anyway, which I could record to without a problem if this were implemented.

Closing for lack of response. Someone else can continue it if they need it: #9

Continued in #11. I argue the use case of moving a file once it's done may be trouble – like @timwedde mentioned, if the temporary folder isn't an option for whatever reason, drive space etc., then it may be best to allow the user to explicitly set the processing/final location.

[alectrocute]

For my specific use case, I'm saving the file externally, so this makes sense. @sindresorhus, thoughts?

I'm fine with adding this, but the docs should mention the different use-cases for the option.

Great! I'll append, squash and prepare this.
