Clarify reserved values for stream types, settings identifiers, frame types, and error codes. 0x1f * N + 0x21 for the value of N = -1 is 0x02. Literal interpretation of the current text includes this as a reserved value. The parenthetical examples given in Section 11.2 make it clear that this was not the intention, rendering this PR editorial. The main motivation of this PR is not that the current text is inconsistent, but that parenthetical examples from 11.2 are necessary to correctly interpret the definitions in sections 6.2.3, 7.2.4.1, 7.2.8, and 8.1. Alternative wordings could be: "0x1f * N + 0x21 for N = 0, 1, 2, ..." "0x1f * N + 0x02 for positive integer values of N" "0x1f * N + 0x02 for N = 1, 2, 3, ..." "0x21, 0x21 + 0x1f, 0x21 + 2 * 0x1f, ..." "a value of at least 0x21 with a remainder of 0x02 modulo 0x1f" "a value of at least 0x21 that is congruent to 0x21 modulo 0x1f" none of which is better than what this PR proposes.
