fix: remove unused @types/long

[SimenB]

#1751 updated to v5 which ships with types. However, the Long type used here seems to be custom and not imported, so this was never used anyways?

protobuf.js/index.d.ts

Lines 1848 to 1862 in 6f0806d

	/**
	* Any compatible Long instance.
	* This is a minimal stand-alone definition of a Long instance. The actual type is that exported by long.js.
	*/
	export interface Long {
	/** Low bits */
	low: number;
	/** High bits */
	high: number;
	/** Whether unsigned or not */
	unsigned: boolean;
	}

Just encountered the same problem. @types/long@4.0.1 is causing an additional Long type that's incompatible with the builtin Long type from long@5.0.0. Had to add import Long from "long"; to generated proto.d.ts to prevent it from picking up the wrong Long from @types/long.

Well, this happens to be harder than I thought - adding this actually breaks some code that depended on import * as Long from 'long' being possible, so it's a breaking change. I will need to roll it back now and think how we could proceed here.

Maybe not rollback, since we actually have more packages doing the same thing with long, but I'll take some time before releasing that to make sure other code I care about does not break because of this. I expect to release this some time next week.
