add nix support (#76)

* Add default.nix for nix support

* Convert to flake

* gitignore before building the source

* Add default.nix and shell.nix for legacy workflows

* Use https://github.com/oxalica/rust-overlay

This one works for development workflow, with a functional rust-analyzer for using with language server support in IDEs.

Also add .vscode/ for pre-configured settings.

* Add documentation

* Restore old TOC and apply TOC patch manually

* Clarify that these two commands are either-or

* Add installing from local checkout (nix-env)

* Add note about version update

* Improve Nix workflow, for zero maintenance

Use https://github.com/nmattia/naersk

This avoids having to set a sha and version in Nix scripts.

* Simplify using crate2nix

Ref: https://www.reddit.com/r/rust/comments/mmbfnj/nixifying_a_rust_project/

* Use rootCrate

* Propagate openssl deps to non-shell build

* Try the oxalica overlay

* Get rid of gitignore crate

cf. https://www.reddit.com/r/rust/comments/mmbfnj/nixifying_a_rust_project/gtsgxal/?context=3

* Configure himalaya crate under defaultCrateOverrides

* Specify openssl in buildInputs

* Make a note about a potential error when using Nix 2.4pre

* Remove PKG_CONFIG_PATH (unnecessary)

* Add cargo-watch

## Nix
[Nix](https://serokell.io/blog/what-is-nix) users might find this section relevant.
### Installing using Nix
If you already have Nix installed (without Flakes), run the following command to install himalaya to your home directory:
```bash
nix-env -if https://github.com/soywod/himalaya/archive/master.tar.gz
# Or, `nix-env -if .` from within the source tree checkout
```
Alternatively, if you use Nix with [Flakes](https://nixos.wiki/wiki/Flakes), you can directly run himalaya without installing it anywhere:
```bash
nix run github:soywod/himalaya
# Or, `nix run` from within the source tree checkout
```
### Development using Nix
To enter a development shell,
```bash
nix develop
```
From here, you have access to all the development tools (Rust compiler, cargo, rust language server, code formatter, etc.) necessary to hack on himalaya.
If you use VSCode, simply open this project folder - and accept the workspace extension recommendations.
#### Troubleshooting Nix
- See [here](https://github.com/soywod/himalaya/pull/76#discussion_r609710097) if you get the `hash mismatch in fixed-output derivation` error.
## Configuration
