ILAMB FLUXNET2015 data fails with TypeError

[wwieder]

Describe the bug
ILAMB seems to run fine, but generates TypeErrors when trying to plot NEE, GPP and other FLUXNET2015 datda. This causes blanks for these column of the ILAMB index page [(see example here])(https://webext.cgd.ucar.edu/I20TR/ctsm5.4.004_bgc_f09_131_HIST/lnd/computed_notebooks/_build/html/ILAMB/index.html).

To Reproduce

• Check out the latest versions of CUPiD, #e6e62cb and conda environments available Jan 16.
• Follow steps on this cheat sheet

Sample error shows

NetEcosystemExchange/FLUXNET2015 ctsm5.4.CMIP7_ciso_ctsm5.3.075_f19_125_HIST TypeError
NetEcosystemExchange/FLUXNET2015 ctsm53041_54surfdata_PPEbaseline_101_HIST TypeError

More details in the ILAMB01.log file here /glade/work/wwieder/CUPiD/examples/key_metrics/ILAMB_output

Expected behavior
No failures in log file

Additional context
FLUXNET2015 data appear to be doubles
/glade/campaign/cesm/community/lmwg/diag/ILAMB/DATA/nee/FLUXNET2015/nee.nc

While CLM history output are floats.
Is this a change that needs to happen internal to ILAMB?

@olyson or @slevis-lmwg can you advise on this?

I'll look through some of Teagan's output to see if she was running into the same issue -- I know we had some trouble getting the right version of ILAMB into externals/ and used in the conda environment, but I think that was all worked out before the 16th...

I've updated to ILAMB 2.7.3, which fixes this issue (and introduces new ones). I'll open a PR to fix this.
