iceberg (ICB) code can't restart from single (rebuilt) restart file

Description

As currently coded the iceberg (ICB) code can only restart from a set of decomposed iceberg restart files (ie. one restart file per processor). It can't restart from a single (rebuilt) iceberg restart file. This is quite a big limitation as it means you can't easily change your decomposition half way through an integration and you can't easily use the restart file from one experiment in another experiment.

I propose to fix this. Can we put this in as a bug fix for NEMO 3.6_stable (and the trunk) or does it need to go on the work plan?

Branch created:

https://forge.ipsl.jussieu.fr/nemo/browser/branches/UKMO/icebergs_restart_single_file

I have managed to get icb_rst_read to do everything with calls to the IOM library with a couple of small tweaks to iom.F90. It can now restart from a multiple-file or single-file icebergs restart and gives bit-comparable results after a one-day. (Also bit-compares with a similar test using the original version of the code). Will fill in a wiki ticket and pass to Andrew for review.
