add umd build of iconv-lite

[gyzerok]

Hello @bpasero!

Here is the UMD build of iconv-lite as we discussed. Currently it depends on the released 0.5.1 version, however building with master doesn't seem to provide any benefits.

The build as is results in 648KiB

            Asset     Size
iconv-lite-umd.js  648 KiB

I was able to shave ~40KiB by excluding utf7 and utf32 encodings.

            Asset     Size
iconv-lite-umd.js  605 KiB

There might be some opportunities to shave more, but I am not as well-versed in encodings topic to do that on my own without breaking something.

I will try to collaborate with the iconv-lite author to see how/if this can be reduced further.

UPDATE 1

It looks like cp949 is also not supported by VSCode. I've excluded it as well from the build.

            Asset     Size
iconv-lite-umd.js  568 KiB

UPDATE 2

Since 0.6.0 is now released, I've updated to use it. Unfortunately that increased the resulting size a bit.

            Asset     Size
iconv-lite-umd.js  583 KiB

UPDATE 3

Thanks to the author of iconv-lite, who pointed out that inline source maps contribute half of the resulting size.

                Asset     Size
    iconv-lite-umd.js  250 KiB
iconv-lite-umd.js.map  249 KiB

@bpasero did you miss my question about source maps?

[bpasero]

@gyzerok oh yeah I missed that. I would not want sourcemaps to be inside any of the web modules, not sure why we decided to add them for semver-umd but I can follow up and ask.

[gyzerok]

@bpasero great! Then once you are able to confirm they are not needed I can make PRs to both libraries to fix it.

[bpasero]

@gyzerok please go ahead with a new PR and I can review when I hear back 👍

What is the size difference?

[gyzerok]

@bpasero check “update 3” in the first post. Will supply PRs tomorrow :)

@gyzerok ah nice!
