tas_input: Minor cleanup

We don't need to copy the whole pair

Resolves a -Wextra-semi warning

clear() when empty is simply a no-op, so we can get rid of the check
here and let the stdlib do it for us.

Gets rid of indirect includes and includes only what the interface
needs.

While we're in the same area, we can also avoid performing std::stoi in
a loop when it only needs to be performed once.

This is only using the input facilities, so we don't need to use the
fully-fleged stringstream.

Same behavior, but without the potential for extra allocations.

This also means we can get rid of the dependency on <regex>

Parameters shouldn't have the colon by their name.

Prevents these values from potentially clashing with anything in other
headers.
