Is this repo still up to date? / factoriodump crashes on requires clause in 1.1 vanilla factorio prototypes

[Scarabytes]

I tried to generate a recipe table for vanilla factorio 1.1 before adding several mods to be calculated, but factoriodump crashed.
It choked on a requires clause within the vanilla prototypes yielding the following error:

> ./factoriodump --calcdir=../factorio-web-calc/ --gamedir=~/Programme/Linux/Steam/steamapps/common/Factorio --prefix=vanilla-1-0 --verbose

The line in question is in base/prototypes/entity/spidertron-animations.lua, however the same problem also occurs in other places if I edit out the __base__/ in this line.
light_positions = require("__base__/prototypes/entity/spidertron-light-positions"),

It seems that __base__ is not being replaced/removed before searching for the file.

Since the webversion can handle 1.1 just fine, I guess either I'm doing something wrong or this repository hasn't been updated. I'd love to get this fixed soon :) Thank you for all your work!
