Reuse allcocated arrays

[hgourvest]

There's no function for writing to a ByteArray pre-allocated in the Source interface.
Such a function would allow us to be more efficient by reusing memory.

fun read(dest: ByteArray, startIndex: Int, endIndex: Int) {
...
}

@hgourvest do you mean a function to access an array backing the source's buffer or a function to read data from a source into an array?

If the latter, then it's already there:

kotlinx-io/core/common/src/Sources.kt

Line 267 in 2f4196f

public fun Source.readTo(sink: ByteArray, startIndex: Int = 0, endIndex: Int = sink.size) {

@fzhinkin Exactly, I totally missed this function. Thank you!
