9) build(npm): Mark the `@chainsafe/blst` peer dependency as optional (#149)

NPM v7 implemented NPM RFC 0025 [1], which makes it install all peer
dependencies even if users of libraries with peer dependencies haven't
included these peer dependencies in their `package.json` files.

Since we have support for the Herumi backend, the `@chainsafe/blst` lib
shouldn't be a required dependency.

To mark it as optional, we're using the `peerDependenciesMeta` option
introduced by NPM RFC 0030 [2].
