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

looks good, also tested on a few datasets and it works thanks!

[TamirCohen]

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 #3265 is fixed and then merge it?

[kerrj]

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

[TamirCohen]

I reran it and it did not work because there are empy comments in:

nerfstudio/nerfstudio/configs/method_configs.py

Line 304 in d6df39b

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