v0.1.2 - Major Bug Fixes

• Makes a change where signed ints are now default for read_long, read_short, read_var_int for both read and write.
• Fixes an issue with read_slice where reading wouldn't be relative to the current offset causing an buffer overflow / underflow.
• Fixes an issue where read_slice did not increment correctly when using.
• Fixes an issue where the primitive types for some methods were incorrect to their naming convention.
