EXRLoader Limited map size

Description of the problem

I baked the scene in Unity and showed it in three.js, and loaded the lightmap in .exr format in three.js. As a result, the exr map of 512 * 512 pixels and below were displayed normally, and the map of 1024 * 1024 pixels and above were displayed normally. Display with red, green and blue noise. for example:

1 exr maps baked by Unity to use as a lightmap，size 1024*1024

1 exr maps baked by Unity to use as a lightmap for the model, size 1024*1024

4 exr maps baked by Unity to use as a lightmap for the model, size 512*512
