Suggestion: ->with_time_zone_same_instant and ->with_time_zone_same_local

[Grinnz]

The section "TIME ZONES" describes how to convert a Time::Moment object to a different time zone using DateTime::TimeZone, either preserving the instant or the local time. I think it would be very convenient to have methods that take a DateTime::TimeZone object, or possibly even a string that can be passed to the DT::TZ constructor (such as you can do with DateTime->set_time_zone), and does the conversion described in those examples. I basically have a function that does this for me at the moment to avoid repeating code, but it would be more convenient to be able to do for example:

my $moment = Time::Moment->from_epoch($epoch)->with_time_zone_same_instant($tz)

The methods can't be named ->with_time_zone_same_instant or ->with_time_zone_same_local since the time zone isn't retained with Time::Moment, perhaps ->with_time_zone_offset_same_instant and ->with_time_zone_offset_same_local, but I'll have to give this some thought. I'm not particular fond of DateTime::TimeZone's API or performance, something I intend to address (and already have done in DPAN code).
