Missing hints used by bootloaders

[MauroToscano]

It seems that some of the hints that the bootloaders use are missing

For example:

cairo-lang/src/starkware/cairo/bootloaders/simple_bootloader/simple_bootloader.cairo

Lines 19 to 22 in 27a157d

	%{
	from starkware.cairo.bootloaders.simple_bootloader.objects import SimpleBootloaderInput
	simple_bootloader_input = SimpleBootloaderInput.Schema().load(program_input)
	%}

[Cevedale]

the error message indicates that some of the required hints used by bootloaders are missing. the hints in question are:

%builtins output pedersen range_check ecdsa bitwise ec_op keccak poseidon

you need to have the necessary declarations for these builtins in your code. relevant modules or files importing or defining these builtins must be included or properly referenced in your script.

from starkware.cairo.common.cairo_builtins import (
output, pedersen, range_check, ecdsa, bitwise, ec_op, keccak, poseidon
)

I found out that there at least one more missing file
Namely this line needs utils.py in simple_bootloader dir, for configure_fact_topologies & write_to_fact_topologies_file func
Also needed for core functionalities like:
load_program
load_cairo_pie,
prepare_output_runner,
write_return_builtins
get_task_fact_topology

tl;dr
cairo-lang/src/starkware/cairo/bootloaders/simple_bootloader/utils.py
is missing also
