v1.3.0

Added

• Lenient parsing: sdpReader.parseLenient(text) never throws, keeps everything the text
  allows and returns {sdp, warnings}. Each deviation that parse rejects becomes a
  warning {code, reason, lineNumber, line, action} with the same reason (and, for the
  first warning, the same line) as the strict error. Trailing spaces/tabs (except on
  s=/i=/u=/e=/p=) and CR-only line endings are handled as well. New types
  SdpLenient, SdpLenientMediaSection, SdpLenientResult, SdpParseWarning,
  SdpParseWarningCode, SdpParseWarningAction, and the type guard
  sdpReader.isComplete(sdp). See "Lenient parsing" in the README.
• sdpValidator.validate(text, {lenient: true}) reports parse warnings as
  lenient:<code> issues and checks the recovered model. SdpIssueCode now includes the
  lenient:* codes (a wider union type).
• wasm: sdp_parse_lenient and sdp_validate_lenient (C ABI), parseLenient and
  validateLenient (ESM bindings); @irbisadm/simple-sdp/wasm has parseLenient,
  isComplete and the lenient validator option. Swift: parseLenient(_:),
  parseLenientJSON(_:), validateLenient(_:type:). Kotlin: parseLenient(sdp),
  validateLenient(sdp, type).

Changed

• sdpWriter.write accepts SdpLenient and throws for a media section without port or
  proto (it used to write m=audio undefined …).
• wasm: a model whose media section has no port or proto is accepted by sdp_write
  and sdp_validate_model like in TypeScript (writing fails with the message above);
  it used to fail with "invalid SDP model".

Fixed

• wasm: a description whose last line ends with a lone CR was parsed differently from
  TypeScript (the CR was dropped); the strict parser now matches TypeScript.
• A malformed a=rtpmap no longer leaves a partially filled codec behind (not visible
  through parse, which throws, but used by lenient parsing).
