function Span::setFlags

Flags, a bit field. Bits 0-7 (8 least significant bits) are the trace flags as defined in W3C Trace Context specification. To read the 8-bit W3C trace flag, use `flags & SPAN_FLAGS_TRACE_FLAGS_MASK`. See https://www.w3.org/TR/trace-context-2/#trace-flags for the flag definitions. Bits 8 and 9 represent the 3 states of whether a span's parent is remote. The states are (unknown, is not remote, is remote). To read whether the value is known, use `(flags & SPAN_FLAGS_CONTEXT_HAS_IS_REMOTE_MASK) != 0`. To read whether the span is remote, use `(flags & SPAN_FLAGS_CONTEXT_IS_REMOTE_MASK) != 0`. When creating span messages, if the message is logically forwarded from another source with an equivalent flags fields (i.e., usually another OTLP span message), the field SHOULD be copied as-is. If creating from a source that does not have an equivalent flags field (such as a runtime representation of an OpenTelemetry span), the high 22 bits MUST be set to zero. Readers MUST NOT assume that bits 10-31 (22 most significant bits) will be zero. [Optional].
