Read.spc leads to error while reading any horiba spc files From 2018 version till now

[GegznaV]

@r-hyperspec/r-hyperspec, I think that the discussion of cbeleites/hyperSpec#124 should continue here.

Some messages by @b8e5n from the original issue:

So far, I had no luck reading Horiba LabSpec generated files using any version after 2017 10 05.
The error message is the following:

Error in x[[jj]][iseq] <- vjj : replacement has length zero

Looking at the code, I haven't found anything that could fix that.

Here is a sample file.
Notice that I renamed it was PDF so GitHub would let me upload it.
I just tried and I cannot read it with the latest version of hyperSpec, which gives me the same issues as I have with other files. The file was generated by Horiba LabSpec 6.
