Build for browser is broken

[lpatiny]

I updated netcdf-gcms to use the new netcdfjs that uses the new iobuffer that use utf8 v3 instead of v2.

chromatography@4.0.0-0 /Users/lpatiny/git/cheminfo/chromatography
└─┬ netcdf-gcms@1.4.0
  └─┬ netcdfjs@1.0.0
    └─┬ iobuffer@4.0.1
      └── utf8@3.0.0 

There is now a problem with the build

cheminfo-build --entry src/index.js --root Chromatography . Error: 'decode' is not exported by node_modules/utf8/utf8.js

@targos Can you help me with this problem ?
