Add Wickra to Time Series

[kingchenc]

Adds Wickra to the Time Series section.

Wickra is an open-source (MIT OR Apache-2.0) technical-analysis library for time series, with a Rust core and a Python package (pip install wickra - precompiled wheels, no build step, no system dependencies).

Highlights:

• 514 indicators across 24 families, every one computed incrementally in O(1) per data point.
• Identical results in batch (whole-array) and streaming (tick-by-tick) modes - bit-exact, fuzzed and 100%-line-covered for all 514.
• Orders of magnitude faster than recompute-on-every-tick approaches for live/online use.
• Same engine is available from Node.js, WebAssembly, Rust and a C ABI, so a model prototyped in Python deploys unchanged elsewhere.
• MIT OR Apache-2.0.
