Subject: [PATCH 1/3] fuzz: Add cifuzz

This PR adds [cifuzz](https://google.github.io/oss-fuzz/getting-started/continuous-integration/) action workflow which is a service provided by oss-fuzz where this project already runs, this helps in catching shallow bugs, regression or build breakage by running fuzzers on PR for ~5 minutes (excluding the build time) on 'release/**' branch.
