numpy v1.24.0 breaks reader IBW

[jotelha]

With numpy 1.24.0, I get

Traceback (most recent call last):

due to this line https://github.com/wking/igor/blob/41952c5fa352fdbe95557a759cdc057fe3ee74f9/igor/binarywave.py#L110 in the igor/binarywave dependency. This does not happen with numpy v 1.23.5.

There was a deprecation warning about this earlier. We need to fix IGOR, although I am not sure how active the project still is.

There is a pull request on igor that addresses this: wking/igor#4 - however, the last commit to igor was in 2016, I am not sure if this will ever be fixed. We may need to implement native IBW support.

I've limited the numpy version in #268 - this is off course only a temporary solution
