Reads a TLS variable-length vector from a byte buffer.

Variable-length vectors are defined by specifying a subrange of legal
lengths, inclusively, using the notation <floor..ceiling>. When these are
encoded, the actual length precedes the vector's contents in the byte
stream. The length will be in the form of a number consuming as many bytes
as required to hold the vector's specified maximum (ceiling) length. A
variable-length vector with an actual length field of zero is referred to
as an empty vector.

@param b the byte buffer.
@param lenBytes the number of bytes required to store the length.

@return the resulting byte buffer.
