feat: increase default Python recursion limit

[1JunGu]

Describe the bug
Server initialization failed. Message: Error sending result: '<fortls.parse_fortran.FortranFile object at 0x7fddce1c8d60>'. Reason: 'RecursionError('maximum recursion depth exceeded while calling a Python object')'

To Reproduce
Initialising Language Server for workspace: *.F with command-line options: --enable_code_actions, --hover_signature, --use_signature_help, --lowercase_intrinsics, --nthreads=4, --incremental_sync

Alternatively, you can try and describe the steps that you followed to encounter the bug:

1. Download fortls using conda, and download Modern Fortran in VS code
2. open my program directory, and click a Fortran file with suffix ".F"
3. See error

Expected behavior
A clear and concise description of what you expected to happen.

Screenshots & Animations
If applicable, add screenshots or GIF/MP4 animations to help explain your problem.

Setup information (please complete the following information):

• OS: Mac intel 2020
• Python Version: 3.9
• fortls Version: 2.13.0
• Code editor used: VS Code
• the Fortran extension for the code editor and its version: Modern Fortran v3.2.0

Maybe the workspace is too large and the stack is too deep?

I probably solve this question temporarily.

1. I add sys.setrecursionlimit(3000) in the fortls shell command.
2. delete some unnecessary codes (may be a lot).

Then I restart the workspace, the Modern Fortran wouldn't issue any errors! Thanks for your excellent software for Fortran programmer!

Yeah, I don't think we can change the recursion limit since it would greatly affect the performance and memory consumption of the language server. I don't remember the specifics on this but when I run into this around a year ago there was a non-trivial reason as to why I could not change it for fortls.

Having said that I don't think this is a bug. It could be considered a feature request, but for me to consider it seriously I would need to know the size of the code base and some info for a MWE. I don't feel comfortable changing the recursion limit (by default 1000) unless there are practical usecases and fortls' performance has been benchmarked before and after.
