feat: Add YCSB-A, B, D, E, and F workloads

[pzittlau]

This pull request introduces implementations for the YCSB-A, B, D, E, and F workloads, complementing the existing YCSB-C benchmark.

Summary of Changes:

• Implemented YCSB-A (50% read, 50% update, zipfian distribution)
• Implemented YCSB-B (95% read, 5% update, zipfian distribution)
• Implemented YCSB-D (95% read, 5% insert, latest distribution)
• Implemented YCSB-E (95% scan, 5% insert, zipfian/uniform distribution)
• Implemented YCSB-F (50% read, 50% read-modify-write, zipfian distribution)
• Added some documentation to for details of the workloads

Additional Notes:

• Each workload is configurable with respect to the number of worker threads, runtime, and data size.
• The version to run can be specified in run.sh

Changes look good, I've pushed a drop cache before measurements begin onto your branch to make the measurements more reliable when they are performed one after another during the 1..=workers loop, the weighting in the zipfian distribution might skew results otherwise.
