[SYNPY-1607] Interface re-write and version un-pinning initiative

[BryanFauble]

Problem:

• The now legacy Synapse python Client requires that the R-interface use specific versions of packages like rjson, reticulate, and R. This leads to significant barriers when using the R client within a larger environment requiring the need to carefully juggle versions of packages.
• The new models interface of the SYNPY client is not yet exposed to the R-client

Solution:

• Enhance synapser package functionality and documentation
• Updated .gitignore to exclude launch.json.
• Added Bryan Fauble as an author in DESCRIPTION.
• Refined dependency specifications in DESCRIPTION for reticulate and rjson.
• Introduced new functions to define class methods and functional interfaces for Python classes in R.
• Enhanced auto-generation of R wrappers for Python classes, including support for functional interfaces.
• Improved documentation generation for functional interface functions.
• Cleaned up shared utility functions and removed deprecated code.
• Updated Python client version to 4.8.0 and adjusted package installation requirements.
• Refactored gateway.py to improve generator handling and annotations.
• Enhanced pyPkgInfo.py to support protocol method detection and documentation extraction.
• Streamlined createRdFiles.R to generate documentation for both Synapse and models.

Testing:

• See this Gist for an example that was tested with this code after installing this branch
