docs: Update readme (#55)

## Description

- remove mention of using raw quinn, since that is no longer possible
- consistently use upper case for QUIC and BLAKE3
- eliminate mention of collections. Collections are just one of many
special cases of hash sequences.
- remove mention of reexport that does not exist anymore

## Breaking Changes

None

## Notes & open questions

Note: the readme is also used from the iroh docs page. That is why I
have a link to "this repository".

## Change checklist

- [ ] Self-review.
- [ ] Documentation updates following the [style
guide](https://rust-lang.github.io/rfcs/1574-more-api-documentation-conventions.html#appendix-a-full-conventions-text),
if relevant.
- [ ] Tests if relevant.
- [ ] All breaking changes documented.

-The requester opens a quic stream to the provider and sends the request. The provider answers with the requested data, encoded as [blake3](https://github.com/BLAKE3-team/BLAKE3-specs/blob/master/blake3.pdf) verified streams, on the same quic stream.

 ## Concepts
 
 - **Blob:** a sequence of bytes of arbitrary size, without any metadata.
 
-- **Link:** a 32 byte blake3 hash of a blob.
+- **Link:** a 32 byte BLAKE3 hash of a blob.
 
 - **HashSeq:** a blob that contains a sequence of links. Its size is a multiple of 32.
