Update rand_distr requirement from 0.5 to 0.6

[dependabot]

Updates the requirements on rand_distr to permit the latest version.

Changelog

Sourced from rand_distr's changelog.

[0.6.0] — 2026-02-10

• Bump to MSRV 1.85.0 and Edition 2024 in line with rand (#28)
• Update rand to version 0.10.0 (#31, #48)

Additions

• MultiDistribution trait to sample more efficiently from multi-dimensional distributions (#18)
• Add WeightedAliasIndex::weights() to reconstruct the original weights in O(n) (#25)
• ConstMultiDistribution trait as support for fixed-dimension distributions (#29)

Changes

• Moved Dirichlet into the new multi module and implement MultiDistribution for it (#18)
• Dirichlet no longer uses const generics, which means that its size is not required at compile time. Essentially a revert of [rand#1292]. (#30)

Fixes

• Fix Geometric::new for small p > 0 where 1 - p rounds to 1 (#36)
• Use direct-minimal-versions (#38)
• Fix panic in FisherF::new on almost zero parameters (#39)
• Fix panic in NormalInverseGaussian::new with very large alpha; this is a Value-breaking change (#40)
• Fix hang and debug assertion in Zipf::new on invalid parameters (#41)
• Fix panic in Binomial::sample with n ≥ 2^63; this is a Value-breaking change (#43)
• Error instead of producing -inf output for Exp when lambda is -0.0 (#44)
• Avoid returning NaN from Gamma::sample; this is a Value-breaking change and also affects ChiSquared and Dirichlet (#46)

[0.5.1]

Testing

• Added building the crate to CI

Fixes

• Fix missing import for no_std builds

[0.5.0] - 2025-01-27

Dependencies and features

• Bump the MSRV to 1.61.0 ([rand#1207], [rand#1246], [rand#1269], [rand#1341], [rand#1416]); note that 1.60.0 may work for dependents when using --ignore-rust-version
• Update to rand v0.9.0 ([rand#1558])
• Rename feature serde1 to serde ([rand#1477])

API changes

• Make distributions comparable with PartialEq ([rand#1218])
• Dirichlet now uses const generics, which means that its size is required at compile time ([rand#1292])
• The Dirichlet::new_with_size constructor was removed ([rand#1292])
• Add WeightedIndexTree ([rand#1372], [rand#1444])
• Add PertBuilder to allow specification of mean or mode ([rand#1452])
• Rename Zeta's parameter a to s ([rand#1466])
• Mark WeightError, PoissonError, BinomialError as #[non_exhaustive] ([rand#1480])
• Remove support for usage of isize as a WeightedAliasIndex weight ([rand#1487])
• Change parameter type of Zipf::new: n is now floating-point ([rand#1518])
