Extensionless imports

[c-vetter]

Finding myself unwilling to use the .js extension for non-js files, I import without file extensions.
Obviously that's a problem when using tsimp, or so I thought, according to the Readme.

But I can just TSIMP_DIAG=ignore the related messages away, and my code runs without apparent issue.
Since my code is linted separately, that shouldn't be a problem most of the time, but it still feels very dirty (because it is).
Officially, there's currently no better way, right?

Are there any plans to support at least "moduleResolution": "bundler" without extensions?

I have to admit, I don't really get the reasoning given in the Readme, mostly because it works anyway.
Although, from my understanding, it probably shouldn't. And that gives me pause.
This part seems related to #16 but I felt our situations and desired outcomes are sufficiently different to warrant a separate issue.
