fix: fixed unexpected behavior when ecol is logical

[cvanderaa]

I adapted readSummarizedExperiment and created a related unit test.

Build seems to fail, the build error is:

Error in gsub("\r\n", "\n", str, fixed = TRUE) : 
  input string 1 is invalid in this locale
Calls: <Anonymous> -> new_rcmdcheck -> win2unix -> gsub
Execution halted

I have no clue what this means...
