Cannot read string beyond 1000 characters

[GetPsyched]

When trying to access a string with the format_value() method, it returns the string normally given it's a relatively short string. But if a string longer than 73 lines is entered, it returns {???} instead of said string. PFA test case which will help reproduce the bug here.

Python resolver has a hard limit on number of characters in a pattern part:

• python-fluent/fluent.runtime/fluent/runtime/resolver.py

  Line 116 in c58681f

  MAX_PARTS = 1000

• python-fluent/fluent.runtime/fluent/runtime/resolver.py

  Lines 145 to 148 in c58681f

  	raise ValueError(
  	"Too many characters in placeable "
  	"({}, max allowed is {})".format(len(fluentish), Pattern.MAX_PARTS)
  	)

That limit results in any pattern part that is longer than 1000 characters to be rejected.

This behavior is unique to Python implementation of Fluent and has no equivalent in Rust or JS versions.
