finch-core/finch-circe 0.14.1

This release only publishes finch-core & finch-circe artifacts and rolls back string-less encoding for Circe. While it was known that byte-targeted printing might be a little slower for small/tiny input (see circe/circe#542), we didn't realize it might hit Finch really hard in the TechEmpower benchmark (-30%).

We're going to put string-less encoding back when we know more about the issue.
