Ensure Content-Length is set for all Responses that need it

Previously responses without explicitly added Content-Length didn't add that header with a 0 value. This made some HTTP clients hang.
Now all responses built with this library will have a default Content-Length header set, unless marked with Transfer-Encoding: chunked

Added ResponseBuilderHeaders.set_content_length(content_length: USize)

This way it is more convenient to set a content-length from a numeric value. E.g. from the size of a prepared array to be passed as HTTP body:

let body = "I am a teapot"
let response = 
  Responses.builder()
    .set_status(StatusOK)
    .set_content_length(body.size())
    .add_header("Content-Type", "text/plain")
    .finish_headers()
    .add_chunk(body)
    .build()

Added BuildableResponse.delete_header(header_name: String)

Previously it was not possible to delete a header, once set it was permanent. No it is possible to delete a header e.g. in multi-stage processing of a HTTP response.

ResponseBuilderBody.add_chunk() now takes a ByteSeq instead of Array[U8] val

This allows to pass String val as well as Array[U8] val to add_chunk.

let response = Responses.builder()
  .set_content_length(7)
  .finish_headers()
  .add_chunk("AWESOME")
  .build()

BuildableResponse.create() now only takes a Status and optionally a Version

The logic applied to set content_length and transfer_encoding from the constructor parameters was a bit brittle, so it got removed. Use both set_content_length(content_length: USize) and set_transfer_encoding(chunked: (Chunked | None)) to set them:

let body = "AWESOME"
let response = BuildableResponse
  .create(StatusOK)
  .set_content_length(body.size())
  .set_header("Content-Type", "text/plain")

Response.transfer_coding() changed to .transfer_encoding()

The wording now is now equal to the actual header name set with this method.

BuildableResponse.set_transfer_coding() changed to .set_transfer_encoding()

Following the Response trait.
