Add RegistroUHEHidrF64 for hidr.dat files that store the volume-cota and cota-area polynomial coefficients in double precision (832-byte records). Hidr auto-detects the format from the file size, recognizing cadastros of 320 or 600 usinas in 792- or 832-byte records, and can convert between precisions via converte_tamanho_registro. Adds a real f64 hidr.dat fixture (320 usinas, full double precision). Also vectorize the cadastro DataFrame construction (build in bulk instead of row-by-row), matching idecomp and substantially speeding up hidr.dat reads; integer columns now use the nullable Int64 dtype. Releases as 1.3.0. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

Resumo
Adiciona suporte ao formato estendido do arquivo
hidr.dat, em que os coeficientes dos polinômios volume-cota e cota-área são armazenados em precisão dupla (registros de 832 bytes). Paridade com a funcionalidade equivalente doidecomp.Funcionalidade
RegistroUHEHidrF64(832 bytes) para os coeficientes em 64 bits.Hidrdetecta o formato automaticamente pelo tamanho do arquivo, reconhecendo cadastros de 320 ou 600 usinas em registros de 792 ou 832 bytes. Tamanhos não reconhecidos geram aviso e assumem o formato f32.
