Import fails silently when not specifying type on crate version 0.8.0

When importing a crate file with a version specifier greater than 0.7.0, the contents of the file are not imported and no error reported or exception raised. (Tested in maya 2024.1 / maya-usd 25.0 and 2022.5 / maya-usd 25.0)

**Steps to reproduce**
1. Unzip the included example somewhere on the test host
2. Launch Maya, ensure maya-usd plugin is loaded
3. Execute the python `cmds.file("/path/to/example/crate_0_8_0.usdc", i=True)` (replacing the path with the location of the unzipped example files)
4. Note that the contents of the scene are unchanged.

**Expected behavior**
1. Execute the python `cmds.file("/path/to/example/crate_0_7_0.usdc", i=True)` (replacing the path with the location of the unzipped example files)
2. Note that the `/World/Cube` prim is imported, and you can see the cube if you frame it in the viewport.
3. Note that the two crate files tested with above differ only at byte 10 (the minor version byte in the header), and are otherwise identical:

```
>fc.exe /b crate_0_7_0.usdc crate_0_8_0.usdc
Comparing files crate_0_7_0.usdc and crate_0_8_0.usdc
00000009: 07 08
```

crate_0_8_0.usdc opens as expected in usdview:

Note that crate 0.8.0 was [introduced in USD 19.03](https://github.com/PixarAnimationStudios/OpenUSD/blob/v19.03/pxr/usd/lib/usd/crateFile.cpp#L292-L294).
