feat(Utils): Add utilility to sort a BED file by chromosome and coordinate

Per discussion in meeting, add another tool to the `utils` directory that can sort an input BED file by chromosome and genomic position.

Instructions/specifications can be found in the [README of the `utils` directory](https://github.com/iRNA-COSI/APAeval/tree/main/utils#Contributing-instructions). In brief, we will need a Dockerfile to install the required dependencies and a shell command/wrapper script to perform the sorting. When it is confirmed the Dockerfile builds locally, it needs to be uploaded to the [APAeval Dockerhub account](https://hub.docker.com/u/apaeval) (ping @yuukiiwa or @uniqueg with a commit ID when it's ready).
