Update column type for raw_data.Demultiplexed_Reads

[TCLamnidis]

Should fix #73.

You need to rebuild the data hash files too

Running data-raw/data_prep.R I got a warning:

> pandora_column_types <- readr::read_tsv(
+   "data-raw/pandora_column_types.tsv",

+   )

One or more parsing issues, call `problems()` on your data frame for details, e.g.:
  dat <- vroom(...)
  problems(dat) 
> readr::problems()
# A tibble: 4 × 5

4   204     8 7 columns 8 columns /Users/lamnidis/Software/github/TCLamnidis/sidora.core/data-raw/pandora_column_types.tsv

It looks like those columns all came from #71. I assumed there to be an extra NA introduced as a copy-paste error and recreated the hash files with that change included, but please check.
