Is your feature request related to a problem? Please describe.

I used visualization of point cloud library.
https://github.com/PointCloudLibrary/pcl
This library has been implemented by C++.

But now, we cannot apply pelemay for elixir project with pcl.

Describe the solution you'd like

Supporting the following functions:

String.replace/2
String.slice/2
String.split/2
String.to_integer/1
Enum.split/2
Enum.reduce/3
Base.encode16/1
length/1
is_bitstring/1

operator
<>

other
calling a function in Enum.map.

Describe alternatives you've considered
No idea

Additional context
None.

String.split/2
Enum.into/2

String.slice/2
Enum.split/2
Enum.uniq_by/2
Enum.group_by/3
