Remove municipality that is not in the Legal Amazon

[lauratregadas]

Passagem Franca (MA) is at 43.95o west. The rule for inclusion in the Legal Amazon is 44o west. Thus, it was mistaknely included by our outside source due to approximation errors.

btw just checked and the package's function that loads municipalities does not include Passagem Franca as part of the Legal Amazon.

municipios_amazonia <- datazoom.amazonia::municipalities %>%
    filter(legal_amazon == 1) %>%
    transmute(municipality_code = code_muni, uf = name_state) %>%
    filter(municipality_code == 2107902)
