Added the 1D BPPC benchmark dataset and the instance generator; Updated README

Please, let me know if any changes are needed.

Thanks for the PR.
I tried the generator program but could not use the Falkenauer instances from BPPLIB. Did you use another format for the input instances?

Edit: I created a new branch new-BPPC-dataset-clem with a few modifications for the generator to handle BPPLIB formated instances. What do you think?

Yes, I recreated Falkenauer's instances, which I obtained (in txt format) from this site:
https://people.brunel.ac.uk/~mastjjb/jeb/orlib/binpackinfo.html

The "Falkenauer-BPP" format of a single BPP instance required by the instance generator, is consistent with the following format:
<bin_capacity> <N> <opt>
<size_1>
<size_2>
.
.
.
<size_N>

where:
N - the number of items,
opt - number of bins in the current best known solution.

Perfect. I agree on that.
It will keep the program more consistent with the BPP(C) environment and make it more universal.

Allright starting a new PR to discuss further.
