/**
 * = The String Table Chunk
 *
 * The String Table ("StrT") Chunk is a mandatory chunk that stores the
 * strings used for example for pattern matching.
 *
 * The chunk itself is just a single binary / byte array.
 *
 * It is defined in `lib/compiler/src/beam_dict.erl` as an `asm` record,
 * where only the `strings` and `string_offset` fields are used.
 *
 * In code chunk, binaries and bitstrings may be referenced by an offset and
 * length to the single binary in the string table.
