Allow users to only include dependencies for relevant table formats during conversion

### Feature Request / Improvement

Currently, the xtable-core library depends on Iceberg, Hudi, and Delta Lake which already results in a wide surface area of dependencies. As the project grows, there may be even more formats leading to an even larger set of dependencies.

The user should be able to add jars to their classpath for the formats that they are interested in and these jars should contain the minimal set of dependencies required for the sync.
