Add higher quality image of IRIS-HEP logo with text

[matthewfeickert]

The current IRIS-HEP logo with the words "iris hep" (the Iris-hep-4-no-long-name series) is of decent quality for a small PNG when used on websites. However, when trying to use the image on other pages in a larger context the resolution isn't very good. Would it be possible to get a higher resolution image of it similar to the Iris-hep-5-just-graphic-large.png that exists?

I created one myself from the SVG that exists in GIMP, but it is several MB in size where the Iris-hep-5-just-graphic-large.png one is much smaller by comparison (~50 KB), so I'm not doing this in a smart manner.
