// * stackalloc does not work, we need pool as consumer is async so it needs Memory not Span
// * this might be most likley overcomplicated and ArrayBufferWriter could be enough, 
//   but it really tries to abuse the chance that read chunks are very small so there is 
//   only one rent from pool and one alloc for final result
// * these 3 methods could be a struct nicely encapsulating functionality but it is used 
//   from async method so struct would be copied all the time
// * these 3 methods could be a class, but I would like to limit allocation to minimum, 
//   so it uses `ref` arguments to delegate `state` to caller and allow keeping it on stack
