You can use a tilesource as source (Image property) for your sprite, no problem:
You then need to define animations in your tilesource, using then sequences from tile A to B, e.g. 1-10.
The problem, I believe you’re referring to, with the linked asset is that each animation is separated:
This is sadly not suited neither for atlas nor tilesource. Spritesheets, even for other engines, usually contain all animations as well. You can join all of those partial spritesheets into one actual spritesheet or export each frame separately and set up an atlas in Defold. With this asset you have aseprite source, so you can go both ways.
There are new Defold Tilemap Editor features released last year that speed up the process a lot (multiple tiles brush selection, copying, pasting, etc)
You can also use external Editors and import to Defold, like mentioned Tiled, but also TileSetter and Sprite Fusion:
