v0.1.5

This version includes the following changes:

• Adding batched simulations feature for MD simulations and energy minimizations with the JAX-MD backend.
• Removing now useless stress_virial prediction.
• Fixing correctness of stress and 0K pressure predictions. In 0.1.4, the stress computation actually involved a derivative with respect to cell but with fixed positions. Now, the strain also acts on positions within the unit cell, thus deforming the material homogeneously. This rigorously translation-invariant stress exempts from any Virial term correction of cell boundary effects. See for instance Thompson, Plimpton and Mattson 2009, eq (2).
• Migrating from poetry to uv for dependency and package management.
• Improving inefficient logging strategy in ASE simulation backend.
• Clarifying in the documentation that we recommend a smaller value for the timestep when running energy minimizations with the JAX-MD simulation backend.
• Removing need for separate install command for JAX-MD dependency.
• Adding easier install method for GPU-compatible JAX.
