Add Brazil's holiday in HOLIDAY_SEQUENCE() and NETWORKDAYS()

[AugustoCL]

Hi, I would really appreciate if you could add Brazilian's holidays to all functions about holidays, so that I can use the tool in my daily work.

Here is the link and the attachment to all future holidays in Brazil https://www.anbima.com.br/feriados/arqs/feriados_nacionais.xls feriados_nacionais.zip

Thanks.
