Add TS types

[kibertoad]

Currently TS import does not work for lambda-local, throwing an error

Could not find a declaration file for module 'lambda-local'. 'D:/sources/project/node_modules/lambda-local/index.js' implicitly has an 'any'
type.
  Try `npm install @types/lambda-local` if it exists or add a new declaration (.d.ts) file containing `declare module 'lambda-local';`

Even very barebones typings would solve that problem.

Thanks for the note. I'm not very confident with TypeScript but I'll see what I can do.

@kibertoad Should be good with 1.7.0
