Background

We've received some feedback from community developers that Lumos is quite large when bundled, which is not friendly for mobile devices

• several different versions of bn.js in the bundle, probably due to browserify-crypto and lumos/hd together
• more than one buffer.js in the bundle
• cost-effective third-party libraries, such as ludash.isequal

Plan

• Refactor the require("crypto") to import by demand
• Unify multiple version dependencies into one version
• Refactor some oversized third-party libraries with simple functions, such as lodash.isequal
• Transpile to both ESM and CommonJS, add the module field to point to ESM result
• Mark the package.json to "sideEffects: false" if it is possible
  • When refactoring, note that @ckb-lumos/config-manager may not be directly marked as "sideEffect: false" since the config.initializeConfig is side-effected
• Decouple the data structure in the @ckb-lumos/rpc from the axios, allowing developers to choose their own HTTP client if they don't want to use the lumos integrated one
