Ability to chunk download from object store

**Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
When downloading large objects (> 300MBs) using object_store crate, I often hit timeout using the default configuration (30 seconds connection timeout). Interestingly, when increasing the timeout, the download speed is actual lower (not sure if it's the same for everyone?).

**Describe the solution you'd like**
I am thinking if it makes sense to chunk a file into smaller ranges (say, 100MB each), and in parallel, download each range with different connection and reconcile them under the same interface.

**Describe alternatives you've considered**
Not sure if such a capability can be composed using the existing interfaces.
