feat(tvix/store): bump fastcdc, use v2020 version r/5925
This switches away from the less canonical "ronomon" version to the implementation as described in the [paper](https://ieeexplore.ieee.org/document/9055082) by Wen Xia, et al., in 2020. That version uses 64-bit hash values and tends to be faster than both the ronomon and v2016 versions, and produces the same chunking as the 2016 version. As per https://docs.rs/fastcdc/latest/fastcdc/#implementations-1, it's the recommended choice. The crate also gained support for streaming version of chunkers: https://docs.rs/fastcdc/latest/fastcdc/#large-data, which might be useful.
