UUIDv5 support

[parkerduckworth]

Introduces a generateUuid5 function, which takes in any identifier and an optional namespace, to generate deterministic UUIDs.

Example:

import { generateUuid5 } from 'weaviate-ts-client';

const withNamespace = generateUuid5('some-string-identifer', 'some-namespace');
console.log(withNamespace);

const withoutNamespace = generateUuid5('some-string-identifer');
console.log(withoutNamespace);

Are there plans to support object parameters, for feature parity with the Python equivalent?
