[Feature Request] Add functions to parse matrices from files

[kMutagene]

Is your feature request related to a problem? Please describe.
There are no direct parsing functions for reading matrices from files.

Describe the solution you'd like
Add such functions, see for example numpy.loadtxt() for reference

Describe alternatives you've considered
Inefficient workarounds include parsing a dataframe with deedle, and doing some conversions. However, if the aim is to only work with the matrix anyway, this is absolutely unnecessary.

Frame.ReadCsv(myPath)
