Update lru dependency

[robinhundt]

Because of a change to the stdsimd nightly feature, num-prime is currently broken on nightly, as it depends on an old version of ahash

ahash v0.7.7
└── hashbrown v0.12.3
    └── lru v0.7.8
        └── num-prime v0.4.3

which uses automatic nightly detection and enables the now removed stdsimd feature (see tkaitchuck/aHash#200). This issue is fixed in a new version of ahash which is now transitively used by the updated dependency on lru.
