Issue 37

[rs-fraser]

PR from forked repo: rspace-os#1

Removes SWORD dependency and non-native upload methods, as raised in #37.
Bumps version number to 2.0.0, as this will be a breaking change for unsuspecting users.

Pull request overview

This PR updates the Dataverse Java client to version v2.0.0 by removing the legacy SWORD-based upload path and standardizing on Dataverse’s native file upload API, along with related dependency/import cleanups and migration documentation.

Changes:

• Remove SWORD upload support (deleted FileUploader, removed uploadFile() API surface, updated package diagram/docs).
• Update code/tests to use native upload (uploadNativeFile(...)) and switch Apache Commons imports to commons-lang3.
• Bump project version to v2.0.0, update dependencies, and add a V1→V2 migration guide + changelog entry.
