dcsctp: Add bounded byte reader and writer Packets, chunks, parameters and error causes - the SCTP entities that are sent on the wire - are buffers with fields that are stored in big endian and that generally consist of a fixed header size, and a variable sized part, that can e.g. be encoded sub-fields or serialized strings. The BoundedByteReader and BoundedByteWriter utilities make it easy to read those fields with as much aid from the compiler as possible, by having compile-time assertions that fields are not accessed outside the buffer's span. There are some byte reading functionality already in modules/rtp_rtcp, but that module would be a bit unfortunate to depend on, and doesn't have the compile time bounds checking that is the biggest feature of this abstraction of an rtc::ArrayView.

dcsctp: Add TLV trait Various entities in SCTP are padded data blocks, with a type and length field at fixed offsets, all stored in a 4-byte header. This is called the Type-Length-Value format, or TLV for short. See e.g. https://tools.ietf.org/html/rfc4960#section-3.2 and https://tools.ietf.org/html/rfc4960#section-3.2.1 This templated class, which is used as a trait[1], is configurable - a struct passed in as template parameter.
