Expand description ASN.1 tag numbers (i.e. lower 5 bits of a Tag
From X.690 Section 8.1.2.2:
bits 5 to 1 shall encode the number of the tag as a binary integer with
bit 5 as the most significant bit.
This library supports tag numbers ranging from zero to 30 (inclusive),
which can be represented as a single identifier octet.
Section 8.1.2.4 describes how to support multi-byte tag numbers, which are
encoded by using a leading tag number of 31 (0b11111). This library
deliberately does not support this: tag numbers greater than 30 are
disallowed.
Create a new tag number (const-friendly).
Panics if the tag number is greater than 30.
For a fallible conversion, use TryFrom
