[Feature Request] Provide overload accepting 'natural' address for wait_until_read_equals(...)

[creiter64]

Hi all,

According to https://vunit.github.io/verification_components/vci.html#bus-master-vci VCI bus master components seem to provide overloads accepting both std_logic_vector addresses as well as natural type adresses.

It would be very convenient to have this for the wait_until_read_equals(...) procedure too.
