Fix IPEA broken links

[ropinho]

refers to issue #24.

The links for download IPEA geographic data were replaced in download.sh script, keeping the structure of data_raw directory required in the generation pipeline.

refer to #1: Also was added a shell code to rename the subdirectories in data_raw keeping the pattern "Base informaçoes ..."

as result:

data_raw
├── DF
│   └── Base informaçoes setores2010 universo DF
│       ├── CSV
│       └── EXCEL
├── PA
│   └── Base informaçoes setores2010 universo PA
│       ├── CSV
│       └── EXCEL
└── RJ
    └── Base informaçoes setores2010 universo RJ
        ├── CSV
        └── EXCEL

12 directories
