Giphy plugin causes slow image loading due to not using limit query parameter

[synth]

Currently, the Giphy plugin does not include limit query parameter and can result in a really slow response from Giphy. I have seen this be upwards of 20s response time before images will load.

In my testing, simply adding a limit parameter to something like 50 will result in sub 1s response times.

This can be worked around by adding limit to the "rating" plugin option, but this is hacky. This plugin should support all the options that Giphy has to be future proof:

UPDATE: I originally thought just limit was the issue. In actuality it was more about the "renditions" used when the picker loads lots of gifs at once.
