case sensitivity for foundry projects causes file to not be found

### Describe the issue:

Slither is unable to locate a library in my Foundry-based Solidity project.

```

### Code example to reproduce the issue:

Console.sol is referenced in the following source files:

contracts/redacted/contracts/governance/ClaimPool.sol:
```
//SPDX-License-Identifier: Apache-2.0
pragma solidity ^0.8.0;

import "forge-std/Console.sol";
...snip...
function isEligible(address _address) public view returns (bool) {
console.log("Checking eligibility of", _address);
...snip...
function hasClaimed(address _address) public view returns (bool) {
console.log("Checking if address has claimed", _address);
...snip...
function claimTokens() public {
console.log("redacted %s", msg.sender);
console.log("%s redacted %s", claimAmount, msg.sender);
...snip...
```

contracts/redacted/contracts/governance/ClaimPoolX.sol:
```
//SPDX-License-Identifier: Apache-2.0
pragma solidity ^0.8.9;

import "forge-std/Console.sol";
...snip...
constructor(address _tokenAddress, address forwarder) {
console.log("Deploying the claim pool", _tokenAddress);
...snip...
```

foundry.toml:
```
[profile.default]
solc = "0.8.16"
libs = ["node_modules", "lib"]
verbosity = 3
fs_permissions = [{ access = "write", path = "./packages"}]
```

Console can be found in:
lib/forge-std/src/console.sol:
```
/ SPDX-License-Identifier: MIT
pragma solidity >=0.4.22 <0.9.0;

library console {
....snip...
```

N.B. There seems to be a case mismatch involved `Console.sol` vs `console.sol` but it doesn't prevent Foundry from compiling; not sure if relevant.

### Version:

0.9.0

### Relevant log output:

_No response_

Start with slither/solc_parsing/slither_compilation_unit_solc.py at the import lookup around line 256 and slither/core/compilation_unit.py around line 231, then inspect crytic_compile's filename_lookup shown in the traceback. Reproduce with the provided Foundry layout and the Console.sol versus console.sol mismatch. Done means Slither can resolve the imported library without the reported ValueError.
