result of importing exr is a plane

Describe the bug
result of importing exr is a plane

To Reproduce
Steps to reproduce the behavior:
1,export houdini heightfield to 16bit floating exr file,
2,Select exr file in godot_heightmap_plugin,
3,Click import in godot_heightmap_plugin,and the result is a plane.

Screenshots
open in krita and can see the channels:

and in plugin the result is just a plane

Environment

• OS: Windows 10 20H2
• NVIDIA 1050ti
• Godot version: Godot_v3.2.4-beta6_win64
• Plugin version: af6a0ac (zip from respositories)
• Renderer used: GLES3

The importer assumes that EXR files use real height range. Your EXR file uses 16-bit floats but they are all within the [0..1] range, so it will look almost flat throughout the terrain.

This could be fixed by allowing to specify a remapping height in the importer, which is an option only available with raw import at the moment.

Another workaround is to use the map_scale property of the terrain node and increase Y a lot, however I never tested it on very large scales, and it might look bad because normals are computed from the source heightmap and will lack precision due to the super-low slope frequency in [0..1].

Thank you! @Zylann it looks good if not select the autoremap 0-1 in Houdini

i thought range 0-1 should be exported then the plugin will remap to min-max height,a llittle bit misunderstanding haha.
