feat: add --namespace CLI option (#22)
Add `--namespace N, -n Wrap types in namespace (disabled by default)` option that will wrap the generated types in a namespace --- Example: `$ npx contentful-typescript-codegen --output ./contentful.d.ts -n Codegen` ```ts declare namespace Codegen { ... } export as namespace Codegen export = Codegen ```
