/**
 * Validates a DF-e (Documento Fiscal eletrônico) access key (chave de acesso).
 *
 * Covers every document whose access key is the same 44 digit string: NF-e (modelo 55), NFC-e
 * (65), CT-e (57), MDF-e (58), CT-e OS (67, the Conhecimento de Transporte Eletrônico para
 * Outros Serviços), GTV-e (64, the CT-e Guia de Transporte de Valores), BP-e (63), NF3e (66)
 * and NFCom (62). The CF-e-SAT (59) is out: its 44 position "chave de consulta" is composed
 * differently. The 44 digits may be split into the printed groups of 4 by whitespace, `.`, `-`
 * or `/`, a run of them between two groups included, the same mask rule `isValidCpf` and
 * `isValidCnpj` follow; a separator inside a group of 4, or any other character, is rejected
 * instead of being stripped. The `NFe`, `CTe`, `MDFe`, `BPe`, `NF3e` and `NFCom` prefixes found
 * in the `Id` attribute of the document's XML (e.g. `Id="NFe3517...`) are stripped before that
 * check, with any whitespace between the prefix and the first group.
 *
 * The key is `cUF(2) AAMM(4) CNPJ/CPF(14) mod(2) serie(3) nNF(9) tpEmis(1) cNF(8) cDV(1)`, with
 * NFCom and NF3e spending position 36 on `nSiteAutoriz` and leaving 7 digits for `cNF`.
 * `tpEmis` must be one of the codes the MOC of that model assigns, so the accepted set changes
 * with the model: 1 to 7 and 9 for NF-e and NFC-e, `{1, 3, 4, 5, 7, 8}` for the CT-e,
 * `{1, 5, 7, 8}` for the CT-e OS, `{1, 2, 7, 8}` for the GTV-e, `{1, 2, 3}` for the MDF-e and
 * `{1, 2}` for the BP-e, the NF3e and the NFCom. Code 8, the authorização pela SVC-SP, is
 * assigned by the CT-e MOC only, never by the NF-e one.
 * The check digit (`cDV`) is a modulus 11 over the first 43 digits, weights 2-9 cycling from
 * the right, where a remainder of 0 or 1 maps to check digit 0.
 *
 * For NF-e and NFC-e the numeric code is also checked against rule B03-10 of the NF-e MOC,
 * which forbids the twenty repeated and sequential `cNF` values it lists and a `cNF` equal to
 * the document number.
 *
 * @param {string} value - The access key value to be validated.
 * @returns {boolean} True if the access key is valid, false otherwise.
