TypeScript version/config is out of date

[mcmire]

• The TypeScript version should match the one specified in the module template
• Currently there is one TypeScript configuration file, tsconfig.json. Instead there should be two, tsconfig.json and tsconfig.build.json
• tsup should be added as a dependency, and tsup.config.ts should be copied over
• package.json is missing types, module, and exports fields
• The build package script should be updated to match the module template, and build:types should be copied
