Description of changes:

Pin litemap and zerofrom versions to prior versions which support our current MSRV rust v1.74.1.

These two dependencies are from the url dep in s2n-quic-qns crate:

Those two dependencies did a release today which bumped their MSRV to rust v1.81. That change breaks our CI, which is noticed in camshaft/bolero#270.

Hence, I am pining the prior versions of those two dependencies, so the integration tests with S2N-QUIC won't fail.

Call-outs:

I have pined those two versions to litemapv0.7.4 and zerofromv0.1.5. If our MSRV got updated to 1.81 or higher, then we can remove those pins.

Tracking this in Issue#2334.

Testing:

CI will test this PR.
