New egg: srfi-189

[Wolfgang Corcoran-Mathe]

Hi,

I'd like to submit a new egg which provides SRFI 189: Maybe and Either
for CHICKEN.  I've run it past test-new-egg, which found no issues.

The egg source can be found at:

https://github.com/Zipheir/srfi-189-chicken

The documentation is at:

https://wiki.call-cc.org/eggref/5/srfi-189

And the release-info URI, for convenience:

https://raw.githubusercontent.com/Zipheir/srfi-189-chicken/main/srfi-189.release-info

Thanks!
