Subject: [PATCH] pin wasm-bindgen-cli to 0.2.100 via overlay

Use an overlay to make pkgs.wasm-bindgen-cli point to
pkgs.wasm-bindgen-cli_0_2_100. This ensures all consumers
of rainix.pkgs get the pinned version.

The latest nixpkgs has wasm-bindgen-cli 0.2.108 which is incompatible
with the rain.wasm dependency that requires 0.2.100.
