Switch ganache-core as a devDependency

[0xjjpa]

• Move ganache-core as a devDependency to avoid embedding it in hopr-core, which is making the compilation of the binary more bloated and difficult.
• Update the required scripts that rely on this dependency to ensure a build can be created successfully w/o this particular dependency listed as a main dependency.
• Deploy a dev version of hopr-core-ethereum with this setup; ensure it it is working by creating a new package and installing it and ensuring its not listed in the node_modules folder.

e.g.

$ mkdir test && cd test
$ test> npm init -y && npm i @hoprnet/hopr-core-ethereum
$ test> npm ls | grep ganache-core
