Description

In the R arrow package, we have a function arrow_info() which provides information on versions and optional components. Python has show_versions(), but it's not as detailed. We can add the following to the Python function:

• List of optional components and whether they are enabled
• Which allocator is used
• SIMD level

Example R output:
