`read_scalar` and `read_scalar_at` allow transmuting values without `unsafe` blocks

The readscalar and readscalarat functions are unsound because they allow transmuting values without unsafe blocks. The following example shows how to create a dangling reference: fn main deriveCopy, Clone, PartialEq, Debug struct S&'static str; impl flatbuffers::EndianScalar for S fn...
