Hello all,

I have a use-case where I want to convert `ByteArray#` to `MutableByteArray#`
without the copy overhead.

Is the underlying memory structure of `ByteArray#` and `MutableByteArray#` the
same?

If I can guarantee that I won't mutate my `MutableByteArray#`, can I use
`unsafeCoerce#` on `ByteArray#` and treat it as `MutableByteArray#`?

Best,
Adithya
