chore: generate simpler lookups from ss58 registry

[harrysolovay]

Should be useful for codegen purposes.

See lookups here.

I don't understand why this needs to be codegenned at all. Couldn't lookups.ts just be

import ss58Registry from "../deps/ss58_registry.ts";

export interface ChainInfo {
  prefix: number;
  network: string;
  displayName: string;
  symbols: string[];
  decimals: number[];
  standardAccount: string | null;
  website: string | null;
}

export const lookup: Record<string, ChainInfo> = Object.fromEntries(
  ss58Registry.map((obj) => [obj.network, obj]),
);

Would be a tiny bit slower. Couldn't help but micro-optimize... in retrospect, the complexity of the build step might make this less worthwhile. Thoughts?

[tjjfvi]

Very tiny, and it's only ever run once. If anything, I would say optimize it by including the specific object in the codegen output (which would be as simple as JSON.stringify(lookup[network]))
