[I] Speedup take_bytes by precalculating capacity [arrow-rs]

   **Is your feature request related to a problem or challenge? Please describe 
what you are trying to do.**
   
   
   We can precalculate the capacity of the value in `take_bytes` based on the 
offsets, while building the offsets.
   This is faster than letting the buffer allocate for us.
   As a bonus, we also save some memory by precisely allocating the resulting 
buffer, instead of overallocating.
