/**
 * Utility functions for handling multiple classifier value options using summed
 * classifiers as specified in the PAY by Square specification.
 *
 * Supports Month Classifier (Table 10) and other classifiers that use summed
 * values.
 *
 * Bit-flag encoding example (Month Classifier):
 * ```
 * Month      | Binary         | Decimal | Bit Position
 * -----------+----------------+---------+-------------
 * January    | 0b000000000001 | 1       | Bit 0
 * February   | 0b000000000010 | 2       | Bit 1
 * March      | 0b000000000100 | 4       | Bit 2
 * April      | 0b000000001000 | 8       | Bit 3
 * May        | 0b000000010000 | 16      | Bit 4
 * June       | 0b000000100000 | 32      | Bit 5
 * July       | 0b000001000000 | 64      | Bit 6
 * August     | 0b000010000000 | 128     | Bit 7
 * September  | 0b000100000000 | 256     | Bit 8
 * October    | 0b001000000000 | 512     | Bit 9
 * November   | 0b010000000000 | 1024    | Bit 10
 * December   | 0b100000000000 | 2048    | Bit 11
 *
 * Combined example:
 *   January + July + October = 1 + 64 + 512 = 577
 *   Binary: 0b001001000001
 *           ^^^  ^      ^
 *           |    |      └─ Bit 0 (January)
 *           |    └──────── Bit 6 (July)
 *           └───────────── Bit 9 (October)
 * ```
