Extend Support for other type of files

[bedantaguru]

Once read_cells supports reading data as it is (see https://github.com/r-rudra/tidycells/issues/7), extend it's the support for other types of files and objects.

• If possible or required, ~depend on wand~. For magic number based file type detection.
• Support for all types mentioned in Data Import Cheat Sheet - by RStudio
• [x] xls : Already supported through readxl and xlsx
• [x] xlsx : Already supported through tidyxl
• [x] doc : Already supported through docxtractr but need a better alternative.
• [x] docx : Already supported through docxtractr
• [x] pdf : Already supported through tabulizer but need either better alternative or more clear guide to the user.
• [x] html, ~xml~ : Already supported through XML possibly need more clear guide and examples
• [x] All kind of delimited files : Few supported through read.csv and readr. Need to support other possiblities.
• [x] All haven types : Check all possible types under haven
  • [x] SPSS
  • [x] Stata
  • [x] SAS
