Describe the bug

When mem is specified with a unit, the mem_mb and mem_mib resources do not make sense. For example, when the request is mem="2G", mem_mb is 1907 and mem_mib is 954.

If 2G is supposed to be gigabyes, then mem_mb should be 2000 and mem_mib should be 1907. If 2G is supposed to be gibibytes, then mem_mb should be 2147 and mem_mib should be 2048.

rule test:
    output: test.txt
    jobid: 1
    reason: Missing output files: test.txt
    threads: 6
    resources: mem_mb=1907, mem_mib=954, disk_mb=1000, disk_mib=954, tmpdir=<TBD>, lsf_project=acc_LOAD, lsf_queue=premium, runtime=2880, mem=2G

Minimal example

Here is a test rule:

rule test:
  output: "test.txt"
  threads: 6
  resources:
    runtime="2d",
    mem="2G"
  shell: ".echo test > {output}"

Additional context

This may be partially related to #2695
I am using the lsf executor plugin, and I am trying to troubleshoot if this is partially due to something I did in the plugin (mem_mib is not shown when not using the cluster and mem_mb is what mem_mib should be if 2G is gigabytes), but I don't remember doing anything that could change the printed resources.
