v0.1.5 Release: PDF Merging and `formalpdf.open` entrypoint

Merging PDFs

import formalpdf

a = formalpdf.open("a.pdf")
b = formalpdf.open("b.pdf")

a.insert_pdf(b, from_page=0, to_page=10)

New Entrypoint

Update enables PDF merging and has a new standard entry point to the code. Following other libraries, preferred entrypoint is:

import formalpdf

document = formalpdf.open("path.pdf")

Instead of:

from formalpdf import Document

pdf = Document("path.pdf")
