Just fixed a long standing bug that prevented structured dtypes of more than 255 bytes in python-blosc2. The new limit is 512 MB, just for the dtype; the limit for datasets continues to be about an Exabyte (2**60 bytes!).

Python-Blosc2 comes with an extensively tested partition sizes algorithm for automatically setting the best chunk and block sizes for you.
But you can always bypass this mechanism for more appropriate fine-tuning in different scenarios 🚀

🚀 Blosc2 supports memory-mapped files for super-efficient data access! 🚀
✨ Why memory-mapping?
1️⃣ No system call overhead for each read/write
2️⃣ Data goes straight from page cache to user space—much faster than traditional I/O!
