lookup('17 09 04')?.description;
// 'mixed construction and demolition wastes other than those mentioned in 17 09 01, 17 09 02 and 17 09 03'
isHazardous('17 06 05');                          // true
mirrorPartners('17 09 04').map(e => e.display);   // ['17 09 01*', '17 09 02*', '17 09 03*']
search('asbestos');                               // entries whose official text matches
