Incompatibility with Node 17

[PanisSupraOmnia]

Hi, currently trying to run npx fitbit-build on Node 17 fails with an error because of the following:

fitbit-sdk-toolchain/src/plugins/typescript/tslib.const.ts

Lines 5 to 6 in 58ea8a7

	const tslibPackage = require('tslib/package.json');
	const tslibPath = require.resolve(`tslib/${tslibPackage.module}`);

The issue seems to be with the exports field in tslib's package.json. It doesn't have package.json as a specified export, so you end up with an 'ERR_PACKAGE_PATH_NOT_EXPORTED' error code. Let me know if there's any other useful info I can provide; I'm new to Node so I don't think I can PR a fix unless pointed in the right direction.

It seems this is a breaking change made in Node 17. We haven't had a new toolchain release since Node 17 was released, so I'd suggest using Node 16 (or 14, both LTS) in the meantime.

Ok, thanks! When I originally ran into this incompatibility I set up a Docker image for builds, so I'll stick with that.
