Description
Hello :)
Is your feature request related to a problem? Please describe.
I need to type a triple norm, like this:

Describe the solution you'd like
A macro such as \rVvert (and \lVvert) would be really appreciated, and would be consistent with the already-existing \rVert and \lVert.
Describe alternatives you've considered
My current workaround is |\hspace{-0.1em}|\hspace{-0.1em}|.
