Pull request overview

This PR adds a new function xdas.picking.tapered_selection to extract portions of waveforms around picks for magnitude estimation and cross-correlation. The implementation includes comprehensive test coverage and documentation.

• Adds tapered_selection function for selecting and tapering DataArray segments based on start/end values
• Includes parallel JIT-compiled implementation using Numba for efficient processing
• Updates test files to use consistent xd import alias for the xdas module
