add imports to generated .d.ts file

[ehallander9591]

protobuf.js version: 6.3.1

Using the pbts tool and WebStorm doesn't like the generated .d.ts file unless I manually add the following lines at the top of the file

import {Writer} from 'protobufjs';
import {Reader} from 'protobufjs';

Is it issue with WebStorm of the typescript compiler?

[ehallander9591]

It would seem that any external package references in the generated .d.ts file would need some sort of reference. Webstorm complains, because tsc complains.

Also need to add 'Method'.

Closing this for now as 6.4.0, which is now released, should solve the issue. Feel free to reopen the issue if necessary.
