Fix parsing of non ascii image names in colmap's images.bin

[TamirCohen]

If colmap image file name is non ascii an error will be thrown in the line current_char.decode("utf-8") while trying to parse the file images.bin It is thrown because it tries to decode a single byte as utf-8, And non ascii chars are represented using more bytes than 1.

My solution proposal is to read all the bytes, and than decode it. I tested it and it worked OK

Thanks @kerrj. Due to an error in the sphynx build I can not merge it (I do not think it is related to my commit). Should I wait after https://github.com/nerfstudio-project/nerfstudio/pull/3265 is fixed and then merge it?

Could you re-run lint please? the linter was updated along with the np 2.0 patch

I reran it and it did not work because there are empy comments in: https://github.com/nerfstudio-project/nerfstudio/blob/d6df39b70d2e0b444178d23b694989e39d624781/nerfstudio/configs/method_configs.py#L304

Should we remove these empty comment in another PR or in this PR?
