* decimal conversion looses value on lower precision, throws error now on overflow.

* fix review comments and fix formatting.

* for simple case of equal scale and bigger precision, no conversion needed.

…with zero (#6805) (#6943)

* fix: Encoding of List offsets was incorrect when slice offsets begin with zero

When encoding offsets the code had an optimization to reuse the offsets if the first offset was zero assuming the slice already pointed
 to first element. But the offset can also be zero if all previous lists were empty. When this occured it mold make all lists in the
slice as empty, even if they shouldn't be.

* Use Buffer::from_slice_ref which will be faster as it doesn't iterate through the slice.

* Avoid copying

* Explicitly reference std::mem::size_of
