This PR introduces a new configuration option to set the maximum number of samples per chunk.
This option is particularly useful to avoid decoding large chunks when querying only a small time range within a day. For example, in Cortex, we typically split queries by "day," which means that even when querying just the last 5 minutes of the previous day, we might end up decoding an entire 8-hour chunk. This results in unnecessary CPU cycles spent processing irrelevant data.
By allowing smaller chunk sizes, we can significantly reduce the overhead of decoding, improving efficiency and performance during partial time range queries.
