Fix test for `remove_spikes` about lumispy HOT 4 CLOSED

Hello!

Just wanted to share that the incriminated test runs fine with my configuration, so I don't think it is an upstream library modification issue:

lumispy 0.2.3.dev0 (main branch)
hyperspy 1.8.0.dev0 (both RELEASE_next_minor and RELEASE_next_patch branches)

============================= test session starts =============================

======================== 2 passed, 3 warnings in 3.57s ========================

Process finished with exit code 0
PASSED       [ 50%]PASSED           [100%]

I have python 3.10.9 and numpy 1.23.5.

Could it be related to the changes in the way random numbers are generated? See hyperspy/hyperspy#3103

Ah sorry I just noticed that the tests have been commented out in the code ^^

Indeed it fails on my machine too.

Changing they way random is seeded does not really seem to change anything though

I think @ericpre is right and it's just a float comparison issue in the test. Test fails based on what random number is generated if I don't let it to a fixed seed of 1.

Changing line 55 to s.data[0, 2, 29] += 1.001 fixes it.

I have opened PR #187 that fixes it
