bug: `yarn` will remove `hyper-nano` binary and `__hyper__` directory on `yarn install`

[TillaTheHun0]

Background

Right now, npx hyper-nano will download the hyper nano binary to the node_modules/hyper-nano/bin directory, and add the __hyper__ directory in the same place, for running services.

Problem

When yarn is ran, this removes the binary as well as the __hyper__ directory, effectively deleting all of the local data. This isn't a great DX for local development

Solution

I will probably need to download the binary to a cache folder outside of node_modules ie. how Cypress downloads its binary

For the __hyper__ folder, we can either also store in the global cache, or place it at the root of the project, similar to how next does it. Right now, hyper-nano just uses the cwd to place the __hyper__ directory, so we will have to add a config option for that.

Workaround

Downloading the binary directly from s3, placing it where you'd like it, and then running it directly, instead of via npx, will get around this issue, until a solution is implemented.

As part of downloading the binary i'll need to also verify the integrity as highlighted in #534. I have a close to working solution for that, just have to tidy it up.
